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.

My coverage tonight and to come

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.

Senate Voting: Another Poor Article By Richard Denniss

It's a shame to have to be distracted from more important things (like counting all the candidate malfunctions this election) in order to deal with an article by Richard Denniss in the Guardian.  I wasn't going to do this, having already done so on Twitter, but unfortunately an email has been seen by me suggesting that a voter took it seriously.  I can scarcely believe this is so, and wonder if I should refer the email to the AFP as a hoax, but the thought of people being Wrong on the Internet about this needs addressing.  Rant warning applies.

To start with, let's declare on Richard's behalf what he failed to admit in his latest article.  Richard Denniss is a former sceptic of Senate voting reform who defended the coercive, corrupted and dangerous Group Ticket Voting system.  In that system, abolished prior to the 2016 election (but still extant in the WA and Victorian upper houses) voters' preferences were being sent they knew not where, and parties could be elected off tiny vote shares based on a weighted lottery of preference deals and effectively random events.  In defence of this old system,  Denniss, of the left-wing Australia Institute, made the ludicrous claim that "the vast majority of Australian voters trust parties to allocate preferences and opt to vote above the line."  Really, Australian voters trust political parties when politicians are among the least trusted occupations?  (OK, the link is only Morgan, but with effect sizes that large, even Morgan can be trusted here!)  We saw exactly how much Australian voters really trusted parties in 2016 when only about 30% of Coalition above-the-line voters, 14% of Labor ATL voters, and 10% of Green ATL voters (and single figures for most minor parties) followed their party's Senate how-to-vote card.  In Tasmania, voters didn't even trust the Labor Party to pick its own candidates properly, and overturned its preselection.

Poll Roundup: Make Newspoll Preferences Great Again!

2PP Aggregate: 51.9% to Labor (last election preferences) (-0.5 since last week)
51.6% with One Nation adjustment
Labor is still winning, but at present polls imply only a modest majority (c. 80 seats) 
Betting markets don't think it's that close

I didn't put out a Poll Roundup last week because there were no major polls.  This week there is a lot more to discuss, starting with United Australia.

UAP Surge - Is It Real?  

After languishing at around 1% in those polls that included them until not long ago, Clive Palmer's United Australia Party has made major inroads in polling in the last month, helped by problems for One Nation, which is not running in every seat anyway.  At the current level, team yellow (unless you're in Tasmania where there are two team yellows) isn't threatening to win Reps seats, but it looks very competitive for the Queensland Senate at least.  That said, media are overplaying the value of the very useful Coalition preferences there, since the Coalition might not get that much over two quotas given the added competition from UAP, and only 30% or so of its voters will follow the card anyway.  The surge is being linked to Newspoll switching to including UAP as a distinct option in its results, which is being interpreted as the party being added to the readout (something which has been thought to overestimate minor party votes).
