Did A Late Switch-Off From Shorten Cause Labor To Lose?

(Note for Tas readers and anyone else interested: Scott Bacon recount thread is here)

Nearly four months after the election, Labor and its supporters are still having great trouble working out what happened.  Ahead in the (faulty) polls for an entire term, well ahead in them for much of it, Labor managed to lose to a government that had seemingly imploded nine months earlier.  There are basically three possible explanations.  The first is that Labor should have won the election, but that at least some central parts of its policy platform were wrong.  The second is that Labor should have won the election and that its policies were sound, but it was let down largely by tactical issues.  The third, about which little has been said, is that Labor could not have won anyway.  (The idea here is that voters no longer care about governance scandals or internal party turmoil so long as they like the PM and the basic way that he is leading.)

A version of the second theory - and by the way, I don't subscribe to any version of the second theory - says that Labor's policy mix was OK but Labor was undone by spurious "death tax" scare campaigns and a massive advertising spend by Clive Palmer against Bill Shorten.  (Those arguing this tend to oversimplify things as if the United Australia Party did little in the campaign but attack Shorten.)  Adherents of this theory seem to have taken succour from findings of a recent ANU study that has been reported as finding that Labor lost because the Coalition made net primary vote gains in a volatile environment during the campaign, and also that a big part of Labor's failure to do likewise was voters switching from Labor to other parties because they became more negative towards Bill Shorten.

Bill Shorten was not a popular Opposition Leader and may well have been electoral lead in Labor's saddlebags all along, although it's not that easy to test that.  But how strong is the evidence that voters deserted Labor in droves during the campaign because their view of Bill Shorten became more negative, whether because of attacks on Bill Shorten or otherwise?  Well actually, looking closely at this study, it's much weaker than the media reports are making it sound.  That's not to say Shorten himself wasn't a major factor in Labor's defeat, just that the evidence that he only became a problem at the end does not stand up.


The survey, among other things, resampled 1692 voters who had given a voting intention (which in a few percent of cases was uncommitted) at some stage during April 2019.  In June 2019 it asked these voters whether they had voted and if so who for.

Some general limitations of such studies should be mentioned.  Firstly, studies involving voters saying how they voted can be unreliable.  There's a vast literature on this going back decades (example summary here).  While recall errors can be linked to memory, especially for voters whose votes jump about a lot, they can also be linked to the voter's present opinions or to voters over-reporting that they voted for the winner.

Secondly, the sample is, after all, another poll at a time when polls have been in trouble.  While its sample size is decent, it is still smaller than some of the major polls that failed.  Its final results (scaled) for voters who did vote were Coalition 42.2 (actual 41.4), Labor 35.4 (33.3), Greens 13.7 (10.4), Others 8.7 (14.8).  This places it way outside the theoretical margin of error for both Greens and Others, and while that's not necessarily a major problem, over-representation of Greens voters is always a worry in terms of potential over-sampling of politically engaged or educated voters generally.

I also want to discuss closely where the Bill Shorten finding comes from.  Voters were asked (Fig 2 p 14) to choose "all that apply from a list of eight pre-specified options, and an ‘Other (please specify)’ category" (my bolding) as reasons why their vote changed.  The following were the pre-specified options:

* Your view on the Prime Minister Scott Morrison changed
* Your view on the Opposition Leader Bill Shorten changed
* Your view on your local candidates changed
* Pressure or advice from your family or friends
* A policy announcement or announcements by the Government
* A policy announcement or announcements by the Opposition
* Your individual circumstances changed
* You moved electorates

My concern about this wording is that limiting the policy aspect to "a policy announcement or announcements" is quite narrow.  It might well focus the respondent's thinking on announcements made during the campaign rather than encouraging them to consider policy more broadly.  For instance if a voter's reason to switch was that they became convinced a policy Labor had announced some time ago was bad, would they necessarily pick this answer?  Or what about if during the campaign they became convinced that Labor could not manage a particular issue area?  I suspect the question design results in an underestimate of the impact of policy on vote-switching.  Given that it's an all-that-apply question, that might not necessarily affect how often voters cited views of the leaders as a factor, but it could well affect the prominence of issues as a factor in vote-switching, including in the subsequent media reporting.

(Peter Brent has reminded me of another point I meant to include in this article but forgot: voters' claimed reasons about why their vote changed could well have been coloured by the aftermath of the election - a point especially applicable to Shorten since he is being widely held responsible for the defeat. After all it's much easier to say your view on Shorten changed than that you were sucked in by a death tax scare campaign.)

Effect sizes

Even ignoring all the above potential issues, the major problem with the media and social media claims about changed views of Shorten blowing the election is that the effect sizes do not bear it out.

32.1% of the April sample intended to vote Labor at that time.  Of these 20.8% said they didn't actually vote Labor, so that's 6.7% who switched away from Labor.  The breakdown of switchers away from Labor was 39.6% Coalition, 27.4% Greens, 7.6% other and 25.4% didn't vote.  At the election 82% of Greens voters preferenced Labor anyway, and if a voter shifted from Labor to Greens then they are probably even more likely to have preferenced Labor, so those switching to Greens would have had very little impact on the 2PP outcome.  44% of Others voters preferenced Labor, but possibly those who switched from Labor during the campaign would have been more likely to do so than those who never intended to vote Labor at all?  Also, a Labor voter not voting only has half the 2PP impact of one defecting to the Coalition.  All up, in this particular sample Labor's total 2PP loss caused by vote-switching was probably not more than 3.9 points.  That's still a lot, but in this particular sample there is a lot of volatility, and all parties are losing points to someone.

We also have a percentage of previous-Labor-intenders citing Shorten as one of their reasons for shifting: 27.7%.  We don't have crosstabs to show whether these were more likely (compared to other switchers from Labor) to switch to the Coalition, the Greens or not voting.  If they were typical, then Labor's net 2PP loss to which perceptions of Shorten contributed drops to about 1.1 points.  This is already not enough to swing the election as only two Coalition seats (Bass and Chisholm) were won by less than this.  But furthermore, it's a multiple-answer question, so some of these voters may have switched for other reasons even without the Shorten factor.

Furthermore it was not only Labor voters who reported switching because their view of Shorten changed.  This was also reported by 14.8% of intending Coalition voters.  Coalition voters who switched (16.5% of an initial 36.9%, so 6.1% of the initial total) reported switching to: Labor 37.2% Greens 16.8%, others 21.2%, didn't vote 24.8%.  But - and this is one of the most crucial issues with this whole thing - while a Labor supporter citing Shorten as a reason to switch from a Labor primary vote could well have still preferenced Labor, it would make no sense for a Coalition supporter citing a changed view of Shorten as a reason for switching their vote to still preference the Coalition.  It wouldn't make that much sense for them to not vote either, although this is still vaguely possible especially if the respondent is giving dishonest reasons for not voting.

Most likely, nearly all the 0.9% 2PP worth of former Coalition voters who cited a changed view of Shorten as a reason for switching from the Coalition, would have either voted Labor or preferenced Labor.  At this point the likely maximum negative impact of Shorten-caused switching on Labor's 2PP vote is dropping still further, to perhaps a few tenths of a point.  And, in a survey of this size, a few tenths of a point is statistical noise.  It's something like five voters.  And that's before we get into any 2PP gains Labor might have made from voters for the Greens or Others who were initially intending not to even preference Labor but were impressed by Shorten during the campaign.  (That's not as silly as it sounds - for instance, Shorten did try to show much more character during the debates than his previous wooden performances.)

This asymmetry applies to Scott Morrison too.  The survey suggests changing views of Scott Morrison were cited in very similar proportions by Labor defectors and Coalition defectors.  Labor defectors were very slightly more likely to cite changed views of Morrison, and as noted above there were also slightly more Labor defectors.  But the important point again is that a Coalition defector who went cold on Scott Morrison may well have not voted, or if defecting to Greens or Others may well have preferenced the Coalition anyway.  But a Labor defector who warmed to Morrison has no reason not to vote, and no reason to defect to Greens or Others while still preferencing Labor.  On this basis, it's unlikely that changed perceptions of Shorten were a major 2PP drain for Labor - it's much more likely that changing perceptions of Morrison were a handy 2PP asset for the Coalition.

Fitting the pattern

There are also good reasons why we should regard the theory that Labor was sunk by voters turning away from Shorten (a theory that I should make clear is not promoted by the study itself, but rather in interpretations of it) as unlikely on the face of it.  Firstly, Shorten was not new; he was a known commodity who had been leader of the party for almost six years including a previous election.  Secondly Opposition Leader personal ratings have historically shown a very weak relationship if any to voter intention (and that applies through the times when Newspoll was accurate, so let's not dismiss that too lightly on account of the 2019 polling failure.)  Elections are usually referendums on governments and Prime Ministers.  The 1993 election was a clear exception and in that case a relationship did develop between the Opposition Leader's personal rating and voting intentions.  This one is not so clear.  Polls underestimated support for the Coalition, but did capture around 1.5 points of movement towards it during April.  However, through this time Bill Shorten's ratings didn't change and basically hadn't changed since October 2018.

Vote shifting and poll failure

It's not relevant to the Shorten narrative, but I should also mention the study in relation to the polling failure.  The study has been used to support a narrative that the polls failed because of a high degree of voter volatility that may have contributed to the ancient enemy of pollsters, late swing.  But what the sample actually shows is not a big deal in 2PP terms:

In the figures above I have redistributed Don't know (April) and Didn't vote (May) and found an expected 2PP based on the actual election preferences.  The actual results are also shown for comparison.

The Coalition made greater primary vote gains than Labor in the sample.  However, Labor also gained - it is just that the raw table disguises this because there are more "Didn't vote" respondents in May than "Don't know"s in April.  Both majors supposedly gained at the expense of Others.  In 2PP terms Others (including UAP and One Nation) were favourable to the Coalition, so this only washes through to about a one-point 2PP shift over the sample period - which is about what the mainstream pollsters got.  The only new thing here then is the idea that the Coalition picked up votes from Others.  But because the results are so weird (with the very low Others vote in the May sample meaning that the ANU's "after" result is even less accurate on an average-error basis than it's "before") that looks a lot more likely to be a peculiarity of this specific study or its sample.  This is backed up by pollsters having been in general wrong not about the Others primary vote, but about the Coalition and Labor primary votes (except for Ipsos who were wrong about the Coalition and the Greens).

The study also cannot demonstrate late swing (eg in the last few days of the campaign after polls had left the field) because its baseline is in April.  And late swing is a theory that is up against the evidence anyway.

I hope this article shows that media narratives about elections based on single studies need to be treated with a great degree of caution.  I considered doing this article as part of a Poll Roundup but was long enough by itself and stood better alone.  A new Poll Roundup may or may not follow in coming days.

Not-A-Poll: Best State Premiers Of The Last 40-ish Years - Final Stage 2

A very long year ago today I started a new series of Not-A-Poll voting for this site's choice of Best State Premier in every state and, eventually, the whole country.  It's been going so long that some of the original contestants, including the current leader, are no longer in the original 40 year window, but I'm going to just retitle it and ignore that.

The votes are in for part 1 of the final for the state winners and the Coalition winner (the latter being an open-primary consolation prize on account of the roughly 80-20 left-right bias in readers on psephology websites).  And here they are:

Total Votes: 201

Why I Don't Prefer Abolishing Above The Line Voting

This week I sent a submission (not yet posted) to the Victorian Electoral Matters committee, concerning the 2018 Victorian election.  Primarily, my submission called for the abolition of Group Ticket Voting in the Victorian Legislative Council and its replacement with a Senate-style system or similar.  This follows a farcical, gamed-to-death 2018 election in which ten micro-party MLCs were elected from primary vote shares eight of them would not have won from under any other system, including two from less than 1% of the vote.

In the event that Victoria won't abolish Group Ticket Voting completely, I suggested the state at least clip its wings a little by:

* allowing an above-the-line preferencing option, so that votes that were just-1 above the line would still be distributed by Group Ticket, but voters could choose to distribute their own party preferences as in the Senate.

* banning preference trading and a range of related consultant activities

* bulk-excluding all parties that fail to clear a primary vote threshold of 4% at the start of the count

Expected Scott Bacon Recount

Resigning MP: Scott Bacon (ALP, Clark)
Recount from 2018 state election for remainder of 2018-22 term 
Contest between Madeleine Ogilvie and Tim Cox
Ogilvie likely, but not certain, to win [UPDATE: Ogilvie has narrowly won.]
Ogilvie may sit as independent and share effective balance of power with Sue Hickey, or may rejoin Labor. [UPDATE: Ogilvie has said she will sit as an independent.]

Recount updates will now be added at the top

Previous Party-Hopping Cases:

As noted below Ogilvie's (under unique circumstances for Tasmania) is the first case of a Lower House MP deserting their party mid-term and sitting with a different party status in 38 years.  However prior to that, this was a more common event.  Here is a not necessarily perfect list since World War II:

* Carrol Bramich (1956) Labor to Liberal (policy tensions and internal issues).  Re-elected as a Liberal.
* Reg Turnbull (1959) Labor to IND (kicked out after refusing to resign as Minister). Re-elected with massive support, later Senator.
* Bill Hodgman (1960) Liberal to IND. Defeated.
* Tim Jackson (1960) Liberal to IND (leadership change fallout). Defeated.
* Charley Aylett (1963) Labor to IND (quit after being disendorsed). Defeated.
* Kevin Lyons (1966) Liberal to IND (preselection issues). Later formed Centre Party and was re-elected.
* Nigel Abbott (1972) Liberal to IND (policy dispute). Defeated.
* Doug Lowe (1981) Labor to IND (leadership change fallout). Re-elected.
* Mary Willey (1981) Labor to IND (leadership change fallout).  Defeated.
* Madeleine Ogilvie (on recount 2019) Labor to IND (multiple factors)

All of the Bramich, Turnbull and Lowe/Willey cases precipitated state elections. 

There is also the case of Gabriel Haros (Liberal) who lost preselection for the 1986 election and ran as an Independent, and probably other similar cases.

It is interesting to note the weak performance of some of these independents at elections.  In the 1964 election Bill Hodgman (Will's grandfather) managed only 475 votes and Charley Aylett only 102.  This didn't stop Bill Hodgman going on to become a two-term MLC for Queenborough (1971-83).

Thursday 12 Sep:

The main takeaway from Ogilvie's Fontcast interview is that Ogilvie has said that she thinks the government should be able to see out its term and that no confidence motions are generally stunts (unless someone does something pretty serious).  It's not a guarantee of confidence to the Liberal Party but it's close, and if that's the way it is then it removes Sue Hickey from the stability equation, since no-confidence motions will now generally be lost 11-13 on the floor depriving Hickey of her casting vote.  This also applies to any matter on which the Liberals and Ogilvie agree.

Wednesday 11 Sep:

Apparently the Mercury will be revealing Ogilvie's decision at midnight. (Done: see here)

UPDATE 9:06: Ogilvie will sit as an independent for the remainder of the term according to the ABC's Emily Baker.  If she does so even for a day she will be the first independent in the House since Bruce Goodluck (elected as an independent for the 1996-8 term, at the end of which he returned to retirement).  She will hence be the first independent as such in the 25-seat parliament that has existed since 1998.  As far as I know she will be the first MP to be elected on a recount but not immediately sit with the party that she stood for.  I think she will also be the first political defector in the House since Doug Lowe and Mary Willey quit the Labor Party following Lowe's removal as Premier in 1981.  (However there have been changes of party allegiance by MPs in the Upper House since, including Terry Martin's expulsion from the Parliamentary Labor Party in 2007.)

People are bound to ask whether she should be allowed to do this, as has been the case with a number of recent insta-rats in the Senate (some of whom were considerably more provoked).  However if a rule is passed that MPs cannot leave their parties, some will stay in their parties while voting however they like, so such a rule may not make any difference.  If the party can force MPs to leave parliament by expelling them (which would be the natural result of such behaviour) then parties could use the same power to exercise absolute control over their MPs, including expelling them over minor disagreements.  So I'm not sure what the solution is.

Tuesday 10 Sep: 

Today's the day.  The recount will be on today and there is a fair chance of it finishing or at least the winner being reasonably clear by 6-7 pm, but it's also possible the TEC will have to come back tomorrow.  Candidates for the recount won't be finalised til after midday.  At this stage I am not involved in the recount but will relay any information that I get.

2:45 The TEC has posted the initial distribution from the recount.  Ogilvie has 42.1% and Cox has 37.4%.  Sherlock has 15.1% and the rest 5.4% between them.  Cox would need a rather steep 61.4% of the remaining votes to go to him to win if none exhausted, which means he must have done badly (or at best about evenly, which isn't enough) on the Bacon-Haddad votes as these have been distributed.  Even more difficult for him now.

4:10 A few minor candidates have been excluded and Cox now needs 62.1% assuming zero exhaust.  Really we are waiting for the final exclusion (Sherlock) to decide it all.

4:40 Down to the last exclusion of Sherlock and Cox now needs 64.8% assuming zero exhaust.  Extremely unlikely.

5:02 Report from Alex Johnston (WIN) that Ogilvie has won by about 200 - if confirmed, that's closer than expected but a win is a win is a win.

5:25 Ogilvie has won by 201 votes (51.0-49.0) after a strong, but not quite strong enough, 56% flow from Sherlock to Cox.  This is the closest Assembly recount for 24 years and the third closest I can find (though records of pre-1950s recounts are hard to come by online) - a Labor recount in Franklin 1995 was decided by 54 votes.  A Liberal recount in Bass 2000 was nearly as close as this one (218 votes).

6:00 Ogilvie has posted a victory video on Facebook.  It doesn't say whether she will rejoin Labor but does comment about "the stability of our important Parliament" and "good governance" - whatever that means.


(Graph above - if the rate of decline since 2017 continues - not that I expect it to - then by the 2026 election there will be no blokes left in the Tasmanian Parliament!)

Tasmanian politics is abuzz with news that popular Clark Labor MP Scott Bacon has said he will resign from parliament for family reasons very soon, triggering a recount for his seat from the 2018 state election.  This article explains how the expected countback (confusingly officially called a "recount") works, pending confirmation that former MP Madeleine Ogilvie will contest it.  It is already known that former radio host Tim Cox will contest the recount.  A Cox win is no problem for Labor, but an Ogilvie win could be a big headache for the Opposition.

A Hare-Clark recount is based solely on the votes that the resigning member had at the point of them being elected.  How close someone did or did not get to being elected in the original count, or how many primary votes they got in the previous election, is not directly relevant.  There are cases where being one of the last candidates excluded is a disadvantage; this isn't one of them.  This recount will be won by one of the three defeated Labor candidates from the last election - but will the winner sit as a Labor MP? 

This is one of the cases where there is the most clear information to look at, because Scott Bacon was elected with over a quota on the first count.  He had a surplus of 932 votes in the original count, but in the recount all his papers will be thrown again at a total value of a quota.  After adjusting for a small loss due to fractions in cutting his original vote down to the 932 votes, the breakdown of his second preferences is approximately as follows:

33.1% Madeleine Ogilvie (ALP)
28.4% Tim Cox (ALP)
17.3% Ella Haddad (ALP) - elected, ineligible for recount
10.5% Zelinda Sherlock (ALP)
3.9% Cassy O'Connor (Green) - elected, ineligible for recount
1.7% Elise Archer (Lib) - elected, ineligible for recount
1.5% Sue Hickey (Lib) - elected, ineligible for recount
3.6% other candidates (all non-ALP)

In the recount, all Bacon's votes are distributed to the candidate who the voter has ranked the highest among the candidates contesting the recount, so Ogilvie will get at least 33.1% if she contests (for example).  If no-one gets more than half of them initially, the lowest vote-getter is excluded and their votes distributed again, and so on, like a single-seat election.

The votes that were 1 Bacon and 2 for an eligible candidate who contests the recount become starting primaries for the recount.  Where an ineligible candidate, or someone who chooses not to contest the recount, was at 2, the vote goes on to whoever was at 3, and so on.  As Ogilvie and Cox each have nearly a third of the total with nearly a quarter to be distributed again, they will clearly be the final two if they both contest; Zelinda Sherlock has a theoretical chance but in practice will not overtake either.  (She would need her share in a three-way split of votes to be 47 points higher than Cox's to even get into second, let alone win.)

Assuming it is Ogilvie versus Cox, 38.5% of the total vote for the recount consists of votes that were 1 Bacon and 2 for somebody who is either ineligible or cannot realistically win.  The question then is simply whether Cox can get a big enough edge on these 38.5% to overhaul Ogilvie's advantage on Bacon's known second preferences.

If no votes exhausted from the recount, Cox would need just over 56% of those remaining votes to flow his way to beat Ogilvie.  A small number of votes will exhaust, so the share he will need of those that don't will be slightly higher.

It will come down mainly to how those voters who voted 1 Bacon 2 Haddad and 1 Bacon 2 Sherlock saw the relative merits of Ogilvie and Cox.  The voters who voted 1 Bacon slightly preferred Ogilvie. Voters whose votes were with Sherlock when she was excluded (these are only an indicator of possible 1 Bacon 2 Sherlock votes) slightly preferred Cox. The preferences of the voters who voted 1 Haddad (again only an indicator of how 1 Bacon 2 Haddad votes might flow) between Cox and Ogilvie are unknown to me.

Overall Cox's task is pretty difficult here and it won't help him that virtually every 1 Bacon vote that wasn't 2 for him was 2 for a female candidate (all else being equal, voters who put males 1 and 2 would be more likely to also put a male 3).  However, it's close enough and Ogilvie was controversial enough that unless Labor have detailed scrutineering data on the contest, I can't be sure that Ogilvie would win.  She is however, in my view, the favourite.

If Ogilvie Doesn't Run

If Ogilvie doesn't run, then Sherlock would need to be ahead of Cox on at least 64.6% of the votes that were 1 Bacon and 2 for neither Cox nor Sherlock. In this case, gender factors would assist Sherlock but given her low profile compared to Cox it would be very surprising if she beat him.  Sherlock has said she will contest.

Ogilvie - Labor Or Independent?

Madeleine Ogilvie's sole term in parliament from 2014-2018 was now and then marked by severe friction with elements of the left and pro-LGBTI forces within the party, chiefly over Ogilvie's conservative positions on social issues of Catholic concern.  Following her loss to fellow Labor candidate Ella Haddad, Ogilvie left the Labor Party.  She ran unsuccessfully as an independent for the Legislative Council seat of Nelson.  (She finished fourth by a narrow margin, and may have won had she managed to overtake eventual winner Meg Webb). 

If Ogilvie contests the recount, wins, and chooses to sit as an independent, then there is nothing Labor can do about it.  Section 232 of the Electoral Act allows a party to order a single-seat by-election if it has run out of candidates willing to contest a recount, but the test is "none of the candidates who were included in the same registered party group as the vacating Member are available to contest the vacancy".  Ogilvie was included in the same registered party group, so Labor could not activate this clause by getting Cox and Sherlock to sit this one out and then claiming they had run out of candidates.

Ogilvie as an independent would further unsettle the already messy dynamics of the House of Assembly, in which the government in theory has a majority but frequently loses votes on the floor because of its rebel Speaker Sue Hickey.  However Ogilvie as an independent would be a bonus for the government, which would have a second route to pass social issues legislation opposed by Hickey.  (Note that this would be no help on issues on which Ogilvie sided with the left - indeed she was one of the early movers on Labor's now abandoned anti-pokies policy.)

Ogilvie as a Labor MP would also be a bonus for the government.  On some social issues conscience votes Ogilvie might still vote with the government, and the fact that Labor had accepted her back into the party after she resigned from it would provide the government with ammunition.  Ogilvie's Nelson run would look like a cynical case of fake independence and Ogilvie would have a lot of explaining to do concerning how she had run for election on a platform of helping the Hodgman government pass its bills (oh yes she actually sorta said that) but was now opposed to them.

Perhaps Ogilvie's presence and some conspicuous public fence-mending with her would help Labor with its current attempts to pivot back to the centre but even that would be embarrassing and the kinds of within-party conflicts involving her as an MP have run deeper than just ideology.  All up, Labor's best scenario here is that Ogilvie would prefer to spend the next 30 months studying space law and posting Youtube music videos on Facebook.

And whoever wins, being rid of such a star performer as Bacon from Labor's Clark lineup is a bonus for the government at the next election, making it harder for Labor to win three Clark seats.

News and other snippets will be added.

Update Thursday 2:40: Re contesting the recount, Ogilvie has said " I’m going to just take little time to consider, and discuss with my family, so I’ll get back to you hopefully in a few days."

Added: Timeline 

There is a two-week period for nominations to be received, which means that the earliest possible date for the recount is September 6 (update: it is actually on on September 10).  This gives the government an extra bonus because Labor will be down one for the first three days (at least) of the September sitting.  There is no pairing convention for casual vacancies (see my article on Rene Hidding's departure re this) and so it appears that the Government will enjoy a 12-11 floor majority in the first week of September and be able to pass legislation without relying on the casting vote of Speaker Sue Hickey.  It will be interesting to see what use, if any, the government makes of this.  (Probably anything all of Hickey , Labor and the Greens would vote against would not get through the Legislative Council anyway.)

Added: Changes of Numbers after Recounts

This recount is unusual in having the potential to change the party numbers on the floor of the Parliament.  As best I can determine recounts started from the 1922 election (replacing by-elections) and there have been 85 of them.  Nearly all have been like-for-like replacements at party level.

The best known example of someone outside the vacating party winning a recount was Bob Brown (IND) taking Norm Sanders' (DEM) place in 1983, despite other Democrats contesting the recount.  There is one other example - in 1961 Reg Turnbull (independent who had been Labor Treasurer in the previous parliament) quit to run for the Senate.  Over 40% of Turnbull's surplus had gone to Labor candidates and only 20% to his independent running mate, so a Labor candidate won the recount.

I have not found any precedent for a member being elected on a recount for the seat of a ticketmate from the original election and then not taking their seat as a member of that party.  However, there is an unsourced Wikipedia comment suggesting that Brian Crawford had left Labor when he initially won a recount for a Labor seat in 1962.  Crawford's win of the recount was successfully challenged in the Court of Disputed Returns on residency grounds (which fortunately for Tim Cox no longer exist), preventing him from taking the seat in any case.  More recently we had Brenton Best saying he would sit as an independent if he won Bryan Green's 2017 recount, but he didn't win.

Sunday - Monday: Ogilvie in

Ogilvie has confirmed she is contesting but has not said whether she will seek to rejoin Labor, and has suggested she will make that decision only if elected.

However, Ogilvie has also made some comments, especially a claim that she would take a "more intellectual approach" to parliamentary tactics, that will do nothing to endear her to those within Labor who do not want her back.  (Update: on Monday there is more of this stuff with Ogilvie claiming that being a "social democrat" means "that I’m allowed to be intelligent and think things through.")

Matthew Denholm has reported that the recount is on September 10, meaning that the government will have at least four days with a floor majority (possibly five as the recount may not finish until noon the following day).  He also reports Ogilvie as seeking confidence that Labor would share her priorities (including traffic congestion) and that there be an end to 'hostility' (Denholm's word, not Ogilvie's) from the Left.

2019 Federal Election: Pollster Performance Review

Welcome (belatedly) to another of my regular pieces that I do after all the election results are finalised and, um, we can't really give this one its usual title this year.  Normally it's called "Best and Worst Pollsters" (see the comparable articles for 2013 and 2016) but this year that title isn't really appropriate.  This year was the year of the great Poll Fail, and when it came to final voting intention polls at least, they all went down together.  The story for seat polling turns out to be a little less clearcut, but not that much.

For all the complaints about "too many polls", the frequency and diversity of Australian polls had been declining at state and federal level in the four years leading up to this election.  At this election there were only five poll series conducting national polls, and of these two were conducted by the same pollster (YouGov-Galaxy conducts both Galaxy and Newspoll polls).

I usually include three categories but this time I'm not going to take tracking too seriously.  As usual the first cab off the rank is ...

Least Worst Final Poll

I usually say the final poll should be the easiest one for the less accurate pollsters to get right, because pollsters can look over each others' shoulders and consider corrections if everybody else is getting something vastly different.  Thus there have been some prior cases where polls that differed from Newspoll for some time have jumped into line with it in their final poll.  This year unfortunately it seems that some pollsters may have taken this concept a little too far - either that or multiple pollsters got to around the same 2PP coincidentally and then decided to self-herd from that point.

EMRS: Labor Down, But Will The Others Voters Please Stand Up?

EMRS July raw figures: Liberal 38 Labor 30 Greens 16 Others 16
Also retro-released EMRS May: Liberal 38 Labor 34 Greens 13 Others 15
Also retro-released EMRS March: Liberal 38 Labor 34 Greens 14 Others 14

Possible "interpretation" figure for July poll: Liberal 41 Labor 32 Green 13 Others 14 (maybe)

Liberals could retain majority in an election "held now" (13-9-3 or 13-10-2), but this would probably depend on what happened with Sue Hickey.

Tasmanian pollster EMRS has released a poll of Tasmanian state voting intention, and has also released the two previous polls in the series (which were not released at the time they were taken; the last released poll was in December).  The polls show a general pattern of a slim lead to the Liberal Government, support for which in the series crashed not long after the March 2018 election, but this particular poll has that gap widening to eight points, with Labor dropping four to 30%.  Labor also polled 30% just after its election loss, and prior to that we have to go back to March 2017 to find it polling worse.  The main beneficiaries are the Greens, who EMRS has long tended to have too high compared to their actual support at elections, but there is also a trend of "Others" continuing to rise, although less than 7% voted for "Others" at the last election.  Who are all these people saying they would vote for someone else, and what are they thinking?

The Labor slump would raise some concerns - as at federal level the party is currently struggling to work out what it stands for, and much of its oxygen on issues is being taken by Sue Hickey.  However, at this stage it is just one reading and we need to see the next one to see if it's a blip or a lasting loss of enthusiasm.

The 2019 House of Representatives results have been finalised, a joyous event that tends to arrive unheralded two to three months after every federal election.  Although all the preference throws had been completed and uploaded some time ago, the final figures importantly include the two-party preference flows by party.  Normally I say that this is very useful for assessing the performance of polls.  At this election the polls failed dismally, mainly because of failures on the Coalition and Labor primaries (except for Ipsos which failed on the Greens primary instead of Labor); nonetheless there will be a final review of them here fairly soon.  This article is a general roundup of other matters regarding the House of Reps figures.

Preference Shifting

The final 2PP result is 51.53% to the Coalition and 48.47% to Labor, a 1.16% swing to the Coalition.

There was a very large shift in the preferences of Pauline Hanson's One Nation.  One Nation preferences flowed only 50.47% to Coalition in 2016 but 65.22% to Coalition in 2019 (even more than the 60-40 split believed to have been assumed by Newspoll after considering state election results).  Overall, preferences from parties other than the Greens and One Nation also flowed more strongly to the Coalition by a few points (53.93% compared to 50.79%) but this was caused by the United Australia Party flowing 65.14% to the Coalition.  Excluding the Greens, One Nation and UAP, Others preferences (50.7% to ALP) were 1.5 points stronger for Labor than in 2016.  It is also interesting that Katters Australian Party preferences flowed 14 points more strongly to the Coalition, very similar to the shift for One Nation.

Poll Roundup: Newspoll's Back, But Should Anyone Actually Care?

This week finally saw the long-awaited return of voting intention polling to the field following the great 2019 election opinion polling failure.  Newspoll returned ten weeks after the election, its longest break between in-field dates ever, and its longest break between releases except for two eleven-week summer recess breaks very early in its history.  The poll, which had the Coalition ahead 53-47 two-party preferred, was the first voting intention poll by anyone since the election.  The ten-week gap without any published attempt to measure voting intention by any pollster was the longest such gap since at least the early 1970s.

The first poll to poke its head over the parapet was of course pelted with eggs on social media.  The strong prior accuracy records of the Newspoll brand, Galaxy Research and Australian federal polling generally were suddenly no protection against charges that polling was no better than astrology.  Much of the pelting came from hopelessly biased Twitter entities who have always hated and distrusted Newspoll because of its Murdoch connections, who used to insist the poll was Coalition-skewed, and now hate it because it got their hopes up for an election their side lost.  So that aspect is a moveable feast of complaint.  But is there any reason for confidence yet that YouGov-Galaxy has identified and fixed whatever went wrong with its polling earlier this year?  Given that it underestimated the Coalition by three points at the election, is there any evidence for confidence that it isn't still doing so?

Well no, there isn't really (though that doesn't mean we should read this poll as really 56-44). At this stage, alas, YouGov-Galaxy and the Australian have done very little that should restore public trust or to even convince us that they care whether their poll will be trusted or not.

Hobart Building Heights Elector Poll

On Monday the Tasmanian Electoral Commission released the results of a voluntary postal elector poll about building heights in the Hobart City portion of Greater Hobart.  This non-binding elector poll has been something of an oddity with a lot of commentary making various claims about it so I thought I'd say a few things about it too.

The turnout

The elector poll attracted a response rate of 42.39%.  This compares to the response rate of 61.94% at the 2018 Hobart City Council election, however that was a record high turnout for Hobart, which had never been above 55.5% before.

I have found data for fourteen previous elector polls going back to the mid-1990s, of which six were held concurrently with council elections and eight were held separately.  Of the eight held separately, I have comparable data for six, and of these turnouts ranged from 83% to 109% of the previous election's turnout for that council (in many cases I have had to use raw turnout figures as I cannot find enrolment data at the time of the poll).  So this elector poll at 68% of the municipality's previous turnout has the lowest comparative turnout rate - and this would be so even without Hobart's 2018 turnout spike.  Issues in comparable elector polls included amalgamation, a proposed major pulp mill, whether to move a council's administration, whether to change a council's name, the location of a waste disposal site and options for a lawn cemetery.  To complete the set, other issues that have been canvassed in elector polls have included water supply and pricing options (including whether fluoride should be added), and the boundaries of a municipality.  It's notable that one of the three pulp mill polls occurred in Hobart, about 200 km away from the pulp mill site.

Tasmanian Local Government Reform Proposals (2019)

The Tasmanian Government has been conducting a detailed review of local government legislation in the state, including electoral rules.  This week this took a major step forward with the release of the Reform Directions Paper.  This outlines a series of possible changes that, based on further feedback, may then appear in the government's draft legislation.  Many of the suggested changes are excellent, in particular reducing the number of boxes a voter must number on the councillor ballot for a valid vote.

My main reason for writing this article is to raise major concerns about some of the proposed options for electing mayors.  The paper gives four possible options for mayors, one of these being the status quo (the mayor is elected directly, anyone enrolled in the council area can run for mayor, the mayor must be elected as a councillor to serve as mayor).  While the status quo has some issues, I don't like any of the three alternatives much, and two of them are especially unsound.  I am writing this article mainly to provide detailed reasons as to why these options are bad, and I encourage anyone who wants to to use these arguments in their submissions, or add others.  While I'm doing this I may as well comment quickly on other aspects of the paper.

There's plenty of time to send a submission with submissions not due until 30 September.  For some reason the official closing time for submissions is 5 pm.

Not-A-Poll: Best State Premier/Chief Minister Of The Last 40 Years: Final Round 1

A loooong time ago when the world was young and innocent I started a runoff series to select this site's choice as best state Premier or Chief Minister of every state and territory in the last 40 years.  The plan was to then run a final with all the state and territory winners together.  Ultimately and unsurprisingly with the left-wing skew of readers on this and other psephology sites, Labor leaders won every round convincingly, so I also ran a runoff to get a token Liberal into the final as well.  Earlier this year I got too busy with all the elections going on to run new rounds when each month started, so I have waited until the elections were over before starting the final.

Our contestants and their histories in this contest are:

NSW - Neville Wran, Premier 1976-1986.  Topped the NSW group first round with 37.8% and thrashed Bob Carr 152-50 in the runoff.

Victoria - Daniel Andrews, Premier 2014-present.  The only current Premier to win a state, Andrews polled second in the Victorian group first round with 25.3%, but with a landslide election victory under his belt, defeated Steve Bracks 158-102 in the runoff (which was postponed in an attempt to reduce contamination from the state election.)

Queensland - Wayne Goss, Premier 1989-1996.  Tied with Peter Beattie on 29.3% in the Queensland group first round then cleaned up Beattie 122-73 in the runoff

Western Australia - Geoff Gallop, Premier 2001-2006.  Gallop won the WA first round narrowly with 32.5%.  The first runoff against Carmen Lawrence was tied 97-97 and I hadn't made a rule for ties so there was a second runoff, which Gallop won 75-71.

South Australia - Don Dunstan, Premier 1967-1968, 1970-1979. Smacked it out of the park with 57.4% in the SA group first round.

Tasmania - Jim Bacon, Premier 1998-2004. Polled 37.3% in the Tasmanian group first round and defeated Lara Giddings 105-84 in the runoff.

ACT - Katy Gallagher, Chief Minister 2011-2014. Polled 40.3% in the ACT group first round and defeated Jon Stanhope 119-52 in the runoff.

NT - Clare Martin, Chief Minister 2001-2007.  The only other leader to win in the first round, with 57.6% in the NT first round (none of the others even managed double figures!)

And the Coalition wildcard is Nick Greiner, NSW Premier 1988-1992, who eventually won a long series of Coalition eliminations, defeating Kate Carnell (ACT), who I had been suspecting would win the Coalition series when I started it, 58-38 in the final.

I've decided not to add any more wildcards.

The rules for the final runoffs are:

* The last candidate in each round is eliminated.
* Any candidate failing to poll 8% in a round is eliminated.
* Ties are resolved in favour of the last leader on primaries at a previous stage at which there wasn't a tie, and failing that in favour of the candidate least recently in office.
* Any candidate who could not mathematically win or tie from their position in a preferential election is eliminated.

Spruiking is, as always, welcome in comments.  Voting for round 1 is open til the end of August.

What Might 2PP Voting Intention Have Really Looked Like In The Last Federal Term?

The 2016-2019 parliament saw Australia's worst failure of national opinion polling since the early 1980s, a failure that was not just a combination of normal errors and a reasonably close election.  Aggregated polling had the Coalition behind for the entire term, at no stage better than 49% two-party preferred, and yet the Coalition won with 51.53% of the two-party preferred vote.

The view that the polls were in fact right all along but voters changed their minds at the last moment (either on election day, or on whatever day each elector voted) fails every test of evidence that it can be put to.  The difference between voting intention for voters voting before election day and on election day is similar to past elections, and if anything slightly stronger for the Coalition.  There was no evidence in polling of change in voting intention through the final weeks, as would have been expected as voters who had already voted reported back their behaviour if the polls were at all times accurately capturing the intentions of the person being polled.  Also if those who had already voted had shifted towards the Coalition as they made their final decisions while those who had yet to vote were yet to do so, there would have been polling gaps of several points between those who had already voted and those yet to do so; this was not the case in the released evidence either.

Most Tasmanian Senate Votes Were Unique

Over the last week or so I've been looking at some statistics relating to the uniqueness (or not) of Senate votes in Tasmania, and some other aspects of Tasmanian Senate voting.  At the moment I'm only doing this for Tasmania, but it can be extended to other states if anyone else wants to do so.  This article has been rated 4/5 on the Wonk Factor scale - it is obviously out and out wonkcore but the maths is not as tricky as in some of the stuff on this site.

All Senate votes are scanned by optical character recognition and the scans are verified by human data operators.  The AEC publishes files of all formal Senate preference votes that can be used by outside observers to verify that the AEC is getting the right results and computing the count correctly.  This year's formatting of these files is a lot more user-friendly than in 2016.  On downloading the files one can find all the numbers recorded as entered in the system for any vote recorded as formal.  Sometimes this includes both above the line preferences and below the line preferences (if both are formal, below the line takes precedence, an issue I will come to later on.)
One minor change is that ticks and crosses are no longer indicated by special characters, an aspect that was the source of some confusion among the easily confused at the last election.

Senate Reform Performance Review 2019

The results of this year's half-Senate election are all in so it is time to observe how our new Senate system performed at its first half-Senate test.  Australian Senate voting was reformed in the leadup to the 2016 election to abolish Group Ticket voting and the preference-harvesting exploits it had become prone to, and give voters more flexibility in directing their own preferences either above or below the line.  In the leadup to that election, many false predictions about Senate reform were made and were then discredited by the results.  I reviewed how the new system went back then: Part 1, Part 2.  Some of the predictions that were made by opponents of Senate reform concerned the results of half-Senate elections specifically, so now we've had one, it's a good time to check in on those, as well as on how this election compared to 2019.  One unexpected issue with the new system has surfaced, concerning above the line boxes for non-party groups, but it is one that should be easily fixed.

Seat Betting As Bad As Anything Else At Predicting The 2019 Federal Election

Advance Summary

1. Seat betting markets, sometimes believed to be highly predictive, did not escape the general failure of poll and betting based predictions at the 2019 federal election.

2. Indeed, seat betting markets were significantly worse predictors of the result than the national polls through the election leadup, and only converged with polling-based models to reach a prediction that was as inaccurate as the national polls at the end.

3. Seat betting predicted fourteen seats incorrectly, but all of its errors in Labor vs Coalition contests, in common with most other predictive methods, were in the same direction.

4. Seat betting markets did vary from a national poll-based outlook in several seats, but their forecasts in such cases were about as often misses as hits.

5. This is the third federal election in a row at which seat betting has failed to show that it is a useful predictor of classic (Labor vs Coalition) seat-by-seat results in comparison with simpler methods.  


With all House of Representatives seats now declared, it's time for a regular post-election feature on this site, a review of how seat-by-seat betting fared as a predictive method.  I have been interested in this subject over the years mainly to see whether seat betting contained any superior insight that might be useful in predicting elections.  In 2013 the answer was a resounding no, in 2016 it was a resounding meh, and surely if seat betting could show that it knew something that other sources of information didn't, 2019 would be the year! Even if seat betting wasn't a very good predictor, if it was not as bad as polling or headline betting this year, that would be something in its favour.

2019 saw the first failure in the headline betting markets since 1993, but it was a much bigger failure than that.  In 1993 Labor were at least given some sort of realistic chance by the bookies, and ended up somewhere in the $2-$3 range (I don't have the exact numbers).  This year the Coalition were $7.00 to Labor's $1.10 half an hour before polls closed - just an implied 14% chance -  and Sportsbet had already besmirched itself in more ways than one by paying out early (which I think should be banned when it comes to election betting, but that's another story).  The view that "the money never lies" has been remarkably immune to evidence over the years, but surely this will be the end of it for a while.

Senate 2019: Button Press Thread


Just starting a thread that will cover the button presses in the remaining Senate races including any interesting information from the distributions of preferences as they come to hand.  I haven't been putting myself in the loop concerning when exactly the button presses will occur, save that Tasmania's will be tomorrow at 10:30 am (open to scrutineers, of which I'm not one this year) with the declaration of the poll on Friday at the same time.  The ACT count is also ready to go (to be delcared on Friday afternoon) and the remaining counts are getting close to completion with relatively few unapportioned or uncounted votes still showing.  The NT button has already been pressed, which did nothing because both major party #1 candidates had a quota.  William Bowe has some comments on NT preferences.

Jim Molan's Senate Result In Historic Context

There is a lot of discussion surrounding Senator Jim Molan's below the line vote in the NSW Senate race.  Misleading arguments about it are being weaponised by some of those who would like to see Molan appointed to the Sinodinos casual vacancy, but there is also a risk that amid all this appreciation of the scale of Molan's result could be lost.

To start with, Molan absolutely is not going to win and has never even looked remotely like being in contention during counting.   But his result is still very significant - in the state in which getting a high below-the-line vote is most difficult (because of historically low below the line rates and also the sheer scale required for an individual campaign), Molan has so far polled just over 130,000 votes (2.8%).  His share should rise slightly based on remaining unapportioned votes but won't be significantly above 3%, if it even reaches that.

How Can Australian Polling Disclosure And Reporting Be Improved?

Australian national opinion polling has just suffered its worst failure in result terms since 1980 and its worst failure in margin terms since 1984.  This was not just an "average polling error", at least not by the standards of the last 30+ years.  The questions remain: what caused it and what can be done (if anything) to stop it happening again.

A major problem with answering these questions is that Australian pollsters have not been telling us nearly enough about what they do.  As Murray Goot has noted, this has been a very long-standing problem.

In general, Australian pollsters have taken an approach that is secretive, poorly documented, and contrary to scientific method.   One notable example of this was Galaxy (it looks like correctly) changing the preference allocation for One Nation in late 2017, and not revealing they had done this for five months (in which time The Australian kept wrongly telling its readers Newspoll preferences were based on the 2016 election.)  But more generally, even very basic details about how pollsters do their work are elusive unless you are on very good terms with the right people.  Some polls also have statistically unlikely properties (such as not bouncing around as much as their sample size suggests they should, either in poll to poll swing terms or in seat-polling swing terms) that they have never explained.

Oh No, This Wasn't Just An "Average Polling Error"

As previously noted, Australian opinion polling has just experienced its first clear predictive failure, in pick-the-winner terms, in a federal election since 1980.  Every campaign poll by four different pollsters (one of them polling under two different brands) had the Labor Opposition ahead of the Liberal-National Coalition (as it had been for the entire term), and yet the Coalition has won an outright majority.  Moreover, polls in the final weeks were extremely clustered, with 17 consecutive polls (plus an exit poll) landing in the 51% to 52% two-party preferred range after rounding, a result that is vanishingly unlikely by chance.  No pollster has yet made any remotely useful contribution to explaining this clustering - those who have even commented have generally said they didn't do it and it must have been somebody else.

The general reaction has been dismay at this unusual level of pollster error in a nation where national polls have a proud record of accuracy.  The Ninefax press, as I call them (SMH/The Age), have even announced that they now have no contract with their pollster, Ipsos, or with any other pollster.  (This may just be for show, since in the past Fairfax often took long breaks in polling after elections.)  News Corp is, for now, standing by Newspoll.  The Association of Market and Social Research Associations has announced a review, although this may be of little value as its only member who is involved is Ipsos.

Gladstone Rises Up: An Error In The 2013 Tasmanian Senate Count

There's apparently not all that much going on in the 2019 election postcount, where the only major dramas left at present appear to be which (probably) left party loses in the Queensland Senate and whether anyone can possibly avoid a recount in Macquarie.  When I compare it to 2016, I'm quite surprised at how busy I'm not.

This means I have time to post something curious I've been meaning to post for some time.  As is well known, the 2013 Senate count was not the Australian Electoral Commission's finest hour.  In Western Australia, the original count had a tipping point between two candidates, neither of whom could win, but the resolution of which determined the final two seats. The loss of 1370 ballot papers meant that it could not be determined who had won, and as a result the entire 2013 WA Senate election had to be voided and rerun in 2014.  This resulted in the resignations of the Electoral Commissioner and the Electoral Officer for Western Australia and major changes to the way ballot papers are handled.  The farce also contributed to the death of Group Ticket Voting at federal level. Under the system we have now the tipping point would have been irrelevant and the lost ballots may well not have affected the outcome.  Many other issues with the AEC's culture were identified in a review and many positive changes have been made.

2019 Federal Election Postcount: Mallee

MALLEE (Nat vs ALP - 19.8%)

Webster (Nat) has won after the seat remained a Nats vs ALP seat by 386 votes.  It is unknown and will perhaps never be known what would have been the Nat-Lib result had Labor been eliminated in third.  (I expect Webster would still have won, but am awaiting the preference distribution.)

In the election leadup I had my eyes on the Victorian seat of Mallee as the most likely to deliver an absolute mess in the postcount.  On election night it seemed to be a bit of a fizzer because none of the independents made 10% in their own right, making it clear that the Coalition was headed for victory.  However the Mallee count has thrown up some interesting complications, and there is a theory doing the rounds that the Liberal candidate Serge Petrovich might be able to defeat Webster if he can make the final two.  I am unconvinced about this theory, firstly because I'm doubting he will make the final two, and secondly because even if he does a rather strong preference flow is needed to get him over the line. I don't think that will happen, Labor HTV card notwithstanding, but in the meantime there's a possibility Mallee will create electoral history.  Never (thanks to Malcolm Baalman for this) has a candidate who finished fourth or worse on primaries in a federal seat reached the final two, and it is possible that this could yet happen.

The Miracle Is Over: The 2019 Australian Federal Election Poll Fail

Nice 2PP.  Shame it's for the other side ...

"I have always believed in miracles" said re-elected Prime Minister Scott Morrison very late on Saturday night.  But many (not all) of us who study national Australian polls and use them to try to forecast elections have believed in a miracle for one election too many.  The reason we believed in this miracle was that it kept delivering.  While polls failed to forecast Brexit, Trump and two UK elections in a row (among other high profile failures) Australian national polls continued to churn out highly accurate final results.  The two-party preferred results in final Newspolls from 2007 to 2016 are an example of this: 52 (result 52.7), 50.2 (result 50.1), 54 (result 53.5), 50.5 (result 50.4).  

Predicting federal elections pretty accurately has long been as simple as aggregating the polls, adjusting for obvious house effects and personal votes, applying probability models (not just the simple pendulum) and off you go; you generally won't be more than 5-6 seats wrong on the totals.  While overseas observers like Nate Silver pour scorn on our little polling failure as a modest example of the genre and blast our media for failing to anticipate it, they do so apparently unfamiliar with just how good our national polling has been since the mid-1980s compared to polling overseas.  As a predictor of final results, the aggregation of at least the final polls has survived the decline of landlines, volatile campaigns following leadership changes or major events, suspected preferencing shifts that frequently barely appeared, herding with the finish line in sight, and come up trumps many elections in a row.  This has been put down to many things, not least that compulsory voting makes polling easier by removing the problem of trying to work out who will actually vote (another possibility is the quality of our public demographic data).  But perhaps it was just lucky.

2019 Senate Postcount: Main Thread

Carry-Over from 2016 Senate: Coalition 16 Labor 13 Green 3 CA 2 AC 1 PHON 1
Expected 2019: Coalition 19 Labor 13-14 Green 5-6 PHON 1 Lambie 1

Currently Coalition is likely to hold 35 seats and need two of Centre Alliance, One Nation and (Bernardi+Lambie) to pass bills.

Welcome to my main 2019 Senate postcount thread.  This will contain outlooks for each state which I will update.  I may move any state that I do any very complex modelling on to a different thread.  In the case of Tasmania, this is only likely to happen if Lisa Singh's below the line vote starts projecting to such a level as to create a serious contest between her and Catryna Bilyk.

Some states will receive much higher detail level than others on account of the competitiveness of races.  Where races appear uncompetitive I won't be posting frequent updates.

2019 House of Reps Postcount

Coalition has won the election, almost certainly with a small majority

Apparently won Coalition 77 Labor 68 Green 1 CA 1 KAP 1 IND 3. 

Seats Assumed Won By Coalition From Labor: Longman, Herbert, Bass, Braddon, Lindsay
Seats Assumed Won By Labor From Coalition: Gilmore, Corangamite, Dunkley
Seat Assumed Won By IND From Coalition: Warringah
Seat Assumed Won By Coalition From IND: Wentworth 

Seats that were being covered but now assumed won: Boothby and Chisholm (Coalition retains), Lilley, Cowan  (Labor retains), Bass (Liberal gain), Macquarie (ALP retain)

This is the main thread for the 2019 House of Reps postcount.  A few days ago I expected I would be unrolling separate threads to unravel three-cornered contests in Melbourne, a complete mess in Mallee and so on, but at this stage none of that has happened.  I have done a quick thread for Mallee though as there's some interest in it.  There is a weird situation in Hunter, where One Nation are currently two points short of beating the Nationals into second, but I don't see any reason to think they can get into second, let alone win if they do.  Indeed the Nationals' margin in second should increase.

2019 Federal: Late Night Live Commentary

Coalition has won the election - small majority likely but perhaps a minority

Apparently won Coalition 74 Labor 64 Green 1 CA 1 KAP 1 IND 3

Seats Assumed Won By Coalition From Labor: Longman, Herbert, Bass, Braddon, Lindsay
Seats Assumed Won By Labor From Coalition: Gilmore, Corangamite, Dunkley
Seat Assumed Won By IND From Coalition: Warringah

Seats currently in doubt (projection = AEC projection)

Eden-Monaro (ALP) - Labor leading on projection
Boothby (Lib) - Liberal leading narrowly on projection
Chisholm (Lib) - Liberal leading narrowly on projection
Cowan (ALP) - Labor leading on projection 
Lilley (ALP) - Labor leading narrowly on projection
Macquarie (ALP) - way too close to call on current projection
Wentworth (IND) - Sharma (Lib) currently well ahead and expected to win

If all current leads hold Coalition will win 77 seats, Labor 67, KAP 1, CA 1, Greens 1, IND 3, with one unclear.

I will be doing live blogging for the Mercury from 6 pm.  The link to the live coverage is here.  The link to the tweet that links to the live coverage is here.  I am not sure yet how long the coverage will go or whether I will need to take any breaks to write articles.  There is an email address on the live coverage for people to ask me questions during the coverage.

I will probably not be checking emails, tweets or for comments on this site regularly during this time, and I ask journalists not from the Mercury not to call me until the live blog has finished.  However if you have interesting scrutineering samples from Tasmania - especially of the rate of below-the-line voting for Lisa Singh in a Senate booth (please say which booth!) - you're extremely welcome to SMS them to me (0421428775) or email them to me (k_bonham@iinet.net.au).  I probably won't be able to reply immediately.

The live blog is paywalled and I don't know if there will be a paywall free link or not. Subscription options are available starting from $12.  (In a kind of reverse Antony Green situation, a public media source did try to poach me for this election but negotiations collapsed from the point where I mentioned the concept of being paid.)

Election Eve: Final Newspoll and Seat Betting Roundup

2PP Aggregate (Final): 51.6 to Labor (Last-election preferences)
(51.3 with One Nation adjustment)
Seat projection assuming polls are accurate 79 Labor 66 Coalition 6 Others

The final Newspoll marks the end of my poll aggregation for this term (barring any late offers) though in the last few weeks, I really needn't have bothered.  Aggregation is most useful when polls are bouncing around, when they have marked house effect differences relative to each other or when there is something happening that is causing voter intention to move.  In the last few weeks, almost nothing has happened and seventeen consecutive polls have landed their 2PPs somewhere in the range 51-52.  There's really nothing for an aggregate to do!

A few election notes (especially re Tasmania)

Just a few quick notes on a number of things, mainly to bring links to various articles to the top.

Election night coverage

On election night I am very pleased to say I will again be live blogging for The Mercury, starting from 6 pm and probably going til about 11 or maybe later, except for any time when I may or may not need to stop blogging and write a quick article for them.  The link will be posted here when known.  It is possible the coverage will be paywalled; if so there are various subscription offers starting from $12, or it may be there will be a paywall-free link.  Once that has been finished, after a brief break I will relocate to home and then continue on here for a while.

Rolling Poll Roundup And Seat Betting Watch: The Final Days

2PP Aggregate 51.5 to Labor (by last-election preferences) (-0.3 since last week)
51.1 with One Nation adjustment
Current seat projection approx Labor 79 Coalition 66 others 6 assuming polls accurate.

The end, it seems, is nigh.  If the (ludicrously herded) national polls are right, the Morrison government would need a huge amount of luck to survive a swing of somewhere around 1.3-2.3%, at an election at which it can afford perhaps two net seat losses.  If the polls on the whole are just modestly wrong in one direction, the Government's chances of survival improve greatly, but the other direction leads to a decisive loss.  The most likely path to survival is a Donald Trump style path - a combination of a modest national polling error and a fair amount of luck with the local breakdowns, but if it happens in this case, after everything, it will be very surreal.

New South Wales 2019: Final Lower House Results And Poll Accuracy

Amid the gearing up for the federal election, the finalisation of the NSW election figures has been largely ignored.  For whatever reason it took a few weeks longer than last time to get to the final 2PP, which is necessary for assessing which polls performed the best among other things.  Though in this case, comparing polls is hardly worth the bother.

Vote Share, 2PP and Preference Change

The primary votes were 41.58% Coalition, 33.31% Labor, 9.57% Green and 15.54% Others (including 3.46% Shooters, Fishers and Farmers with the rest led by 1.53% Sustainable Australia, 1.52% Keep Sydney Open and 1.51% Animal Justice.) The 2PP was 52.02% to the Coalition, a 2.3% swing away from their 2015 result.

The overall two-party preference flow barely changed at all, with 33.0% of preferences flowing to Labor (-0.6%), 14.0% to Coalition (-0.8%) and 53.0% exhausting (+1.4%).  But overall what happened here was that the flow of Greens preferences strengthened, but this was cancelled out by the Greens' share of all non-major voting falling from just over 50% to just 38%.  In those seats in which Greens candidates were excluded, the preferences distributed at that stage flowed 51% to Labor with just 9% to Coalition and the rest exhausting.  The stronger flow in Lismore, 72%, was among the highest and was crucial to winning the seat, while East Hills would have been extremely close had Labor managed to match the state swing there.

Poll Roundup And Seat Betting Watch: The Polls Are Getting Closer (To Each Other)

2PP Aggregate 51.8 to Labor (2016 preferences) (-0.1 since last week)
51.4 to Labor (with One Nation preference adjustment)
Current seat projection assuming polls are accurate c. 80 Labor 65 Coalition 6 crossbench (+/- lots!)
Polls appear to be "herded" which can increase risk of error

Time for another instalment of the week in polling and seat betting, delayed slightly by an interstate trip.  As of last week the United Australia Party were going through a bit of a purple patch, polling 5% in Newspoll and above their 2013 result in a bunch of seat polls.  This hasn't lasted; all their poll results this week have been in the 3-4% range, and in three WA YouGov-Galaxy seat polls they did worse than their 2013 results (in one case much worse; the other two only very slightly.)

This week's action in the minor party primaries came from the Greens who polled 14% in Ipsos, 11 in Morgan, 12 in Essential and 9 in Newspoll.  Ipsos (especially) and Morgan have form for exaggerating the Green vote and Essential's reading of the Green vote lately has been quite volatile, but even so the party doesn't seem to be in too bad shape, with the issues mix at this election helping it (that is an understatement.) That said, the Greens have finally struck the candidate problems that have hitherto affected everybody else.
