Will Hodgman Resignation And Recount

Retiring MP: Will Hodgman (Liberal, Franklin)
Recount from 2018 election for remainder of 2018-22 term
Nic Street expected to win recount if he contests, otherwise Simon Duffy
Replacement will be a Liberal
Peter Gutwein/Jeremy Rockliff to be elected unopposed as leader/deputy after Michael Ferguson/Elise Archer withdrew

----------------------------------------------------------
Monday Jan 20 updates

Today's the day, but there has been remarkably little news about the expected ballot and a lot of speculation.  No Liberal MP has publicly endorsed either ticket.  The belief among a few journalists I've spoken to over the weekend is that Gutwein appears to either have the upper hand or at least have enough to tie, but these things can change or can be unreliable.  Some outlets have reported Mark Shelton and (perhaps surprisingly) Joan Rylah as undecided votes.  Gutwein has been firming on the Sportsbet market (1.36 vs 2.90, having at one stage been only just ahead) but this is the same firm that had the Liberals at $15 to win an outright majority six weeks out from the election.

11:45 Ferguson/Archer withdraw: The Ferguson/Archer team has withdrawn, presumably because they did not have the numbers.  Gutwein/Rockliff will be elected unopposed.

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.

EMRS: No Real Change Since Election

EMRS: Liberal 47 (-3.2 from election), Labor 30 (-2.8), Green 14 (+3.7) Ind/Other 8 (+1.2)
Interpretation: Liberal 49.5 (-0.7) Labor 31.5 (-1.3) Green 11 (+0.7) Ind/Other 8
Outcome if election "held now" based on this poll: Liberal majority government (c. 13-9-3)
However it is unlikely in practice Greens would be in a position to regain Bass so quickly.
Poll provides no evidence that any party's support has changed.

The December 2017 EMRS poll, taken three months out from the 2018 state election, proved to be completely unpredictive of the outcome.  It had a 17% swing against the Government (the actual swing in the end was 1%), a 3.2% swing to the Greens (the actual swing was 3.5% against) and an 8% vote for the Jacqui Lambie Network (who in the end got 3.2).  If a poll taken three months out is predictively worse than useless, what can we say of one taken two months into an expected four-year term?

Tasmania 2018: But What Does It All Mean?

LIBERAL 13 LABOR 9 GREEN 1 UNDECIDED 2
Undecided: Franklin - Liberal vs Green - tossup
Undecided: Bass - Labor vs Green vs Liberal - Labor slightly favoured, Liberal chance remote

After the last Tasmanian election, I saw no need to unpack possible meanings of the result, as I thought it was all obvious to anyone who had followed the state's politics through that time.  This one, however, is different, though I certainly won't claim to have all the answers.  A government that seemed to be sleepwalking to a loss of majority has rebounded to the point of suffering just a trivial swing against it.  The Labor opposition did rebound to a degree, but mostly at the cost of the Greens.

Some facts and stats

A few facts about the election first.  For the first time since the 1970s, and the first time for a conservative party since 1912-3, the Liberal Party has topped 50% of the primary vote for a second election in a row.  The charge was led by Premier Hodgman, whose 38.3% is the highest candidate vote since Robin Gray in 1986.  (Hodgman will also break Doug Lowe's 1979 record for the largest number of votes recorded by a candidate, though this record is somewhat meaningless because of population growth. Lowe's record for the highest candidate percentage, 51.2%, may very well never be beaten - and I don't think the fact it was achieved before Robson Rotation really makes much of a difference.)

Tasmania 2018: EMRS Has It A Little Closer Than ReachTEL

EMRS: Liberal 46 Labor 34 Greens 12 JLN 4 Others 3
EMRS has historically skewed against Labor and to the Greens by a few points, but will not necessarily do so this time (given Green vote is so low and methods changes)
On this poll Liberals would probably win a majority (c. 13-10-2) but would depend on seat breakdown 
Aggregate of all polling 13-10-2
Current prediction 13-10-2

The second independent poll of the Tasmanian election campaign (now in its final week - see guide) is out and shows a 12-point lead to the Liberal Party over Labor, compared with the 15.8 point lead in the ReachTEL after redistributing "undecided" voters.  This is a 12-point gain to the Liberals compared to the December EMRS (which showed the parties tied) and I believe that this is the largest poll-to-poll gain by a party in EMRS history.  However, there are close similarities with the recovery of the Lennon Labor government from a seemingly majority-losing position in late 2005 to a winning one by the time of the March 2006 poll.

Tasmania 2018: ReachTEL Confirms Liberals Probably Winning

ReachTEL (after redistributing undecided) Liberal 48 Labor 32.2 Green 12.5 JLN 5.3 (4.0 excluding seats not contested) Others 2.1
ReachTEL has historically skewed against Labor and to the Greens in Tasmanian elections
Most likely breakdown if raw figures are correct 13-9-3 or 13-10-2 (close to 14-8-3 or 14-9-2)
Most likely breakdown based on figures corrected for past skew 13-10-2 (close to 13-11-1 or 12-11-2)
Aggregate of all polling 13-10-2
Current prediction 13-10-2

The first independent poll of the Tasmanian election (see my main guide page) has been released and it confirms growing suspicions over the past few weeks that the Liberals will probably retain an outright majority, although it may well be a majority of one.  Moreover given the historic tendency of ReachTEL to skew against Labor and to the Greens, the poll can be taken as suggesting that the Greens are in serious trouble and that none of their seats are safe.  I am a little sceptical of whether that past pattern will continue.

Tasmania 2018: What Happens If No Party Wins A Majority?

UPDATE 28 Jan: Parts of this article relating to Labor are now out of date with ABC TV News tonight clearly showing Labor leader Rebecca White saying that Labor will not govern in minority.   See update at bottom of article.

UPDATE 31 Jan: And I missed it at the time but Will Hodgman also on the first day of the campaign said "We will govern in majority or not at all [..]"
--------------------------------------------------------------------------------------------

Advance Summary 

1. Despite widespread reports to the contrary, neither major party appears to have given an explicit commitment that they will not govern in minority should no party win a majority at this year's Tasmanian state election.

2.  The leaders have only given various, often ambiguous, commitments that they will only govern "alone" or that they will not govern via deals with, or with the support of, minor parties.

3. A widespread belief that if there is no agreement between parties the Liberals would be forced to keep governing appears to follow instead from a direction from Governor Underwood to Premier Bartlett to form a government in 2010.

4. In theory, a government in such a position could instead resign, but this seems unlikely in practice.

5. In the absence of at least a tacit arrangement between parties, the most likely outcome of a hung parliament would be the Liberal Party continuing in minority unless/until the government was defeated on the floor of the House.

6. For this reason, a parliament without any party holding a majority might (if all parties stuck to their pre-election commitments but no party gave any new ones) be unusually unstable.

2018 Tasmanian State Election Guide: Main Page

The election has been won by the Liberal Party. Go here for postcount links:

Bass
Braddon
Denison
Franklin
Lyons

===================================================================

Welcome to the main page for my 2018 Tasmanian state election coverage.  This page will carry links to all the other articles about the election that I write prior to the close of polling, and will contain general big-picture stuff and links to all the specialised articles (once these are written).  It will be updated very frequently.  However, one thing I am doing differently from my 2014 guide is that each electorate has its own guide page.  Note that these are my own guides and I reserve the right to inject flippant and subjective comments whenever I feel like it; if you do not like this, write your own.

If you find these guides useful, donations are very welcome (see sidebar), but please only give me money if you can afford to.

New Commissioned Tasmanian Polls

Tasmanian state election season is heating up with regular policy announcements (at least from the government) and rumours that the election could be called this weekend for March 3 (what, not the same day as South Australia again?  Surely too good to be true!)

I expect we will have some public polling before too much longer so we can see if the Liberals have recovered from an utter stinker from EMRS late last year, but in the meantime the shady forces of commissioned polling are out there doing their stuff.  This week Tasmanians were treated to not one but two rounds of robo-bombardment.  A diabolically odd anti-pokies question left many scratching their heads (especially pokie opponents) while reports of the warm fuzzy niceties of the other poll on offer sparked Twitter responses like this:


OK, there was actually only one response like that, but this poll even asked voters if they liked Tasmanian political leaders as human beings!  It also asked if voters thought Jacqui Lambie was good at her job, which came as a surprise to me, because I didn't know she had one anymore.  


MediaReach Liberal Poll

Anyway, the long and cuddly robopoll has seen the partial light of day first, and what this is is a MediaReach internal poll commissioned by the Liberals, with a sample of a whopping 3,000.  Methods details are bereft - I've seen a claim it only canvassed landlines, but I constantly see the same claim about other pollsters who ceased doing so years ago - so there's not much more to say about it yet.  

Now, I'm not sure if ReachTEL weren't available (they're prim and proper about refusing dual commissions if they have a conflict in a market) or if the Liberals just don't trust them anymore, but MediaReach was a novel selection indeed.  This pollster hasn't been seen in Tasmania before and its only previous testable public results have been in the NT, where it was out by about five points 2PP in an electorate poll and a territory election poll.  So what do we know about its accuracy in the Tasmanian or indeed any similar context?  Diddly-squat.  Add to that that it's a commissioned poll that wouldn't have seen the light of day had the Liberals not liked the result, and the only weight I can aggregate it at is zero.  Still, it will be fascinating to see how it scrubs up on election day.

Actually, if I did aggregate this poll it wouldn't make much difference anyway.  Oddly giving results to two decimal places (not that there is anything actually wrong with that) the poll has the following results:

Liberal 41.12
Labor 34.29
Green 12.81
Lambie Network 6.19
leaving 5.59 for others.

EMRS Says The Wheels Are Falling Off

EMRS (Tas State) December: Lib 34 ALP 34 Green 17 JLN 8 IND/Other 7
Appears to be lowest Liberal primary for 11 years
Interpretation (based on historic skew) Lib 35.5 ALP 37.5 Green 14 JLN 8 Others 5

Modelled seat results based on this poll if election "held now": hung parliament with 10-10-4-1 (Liberal, Labor, Green, JLN) with next most likely outcome 9-11-4-1
Rolling aggregate of all state polls 12-10-3-0 
Rebecca White increases Preferred Premier lead over Will Hodgman to 13 points

If the December EMRS poll is to be believed (see also the helpful trend tracker), the Hodgman Government is currently headed for a Campbell Newman-like reversal of fortune at the 2018 Tasmanian state election.  Having won a massive victory from Opposition at the 2014 state election, the current poll suggests Hodgman's government, much like Newman's, could be going straight back where it came from and that election night could be carnage with incumbents losing all over the place - to Labor, the Greens, the Lambie Network and their own party.  On a like for like basis (which is rather difficult to follow through old EMRS poll reports) this seems to be the Liberals' lowest primary in an EMRS poll since August 2006.

EMRS: White Lead Is A Big Problem For Liberals

EMRS August Lib 37 ALP 34 Green 16 Ind 6 JLN 5 Other 1
Interpretation Lib 39 ALP 38 Green 13 Others 10
Modelled seat result based on this poll if election held now: Liberal 11-12 seats Labor 10 Green 3-4 
Warning: Polls are snapshots, not forecasts
Preferred Premier Rebecca White leads Will Hodgman 48-37

A new EMRS poll of state voting intentions is out.  Also see the trend tracker. The party breakdown shows scarcely any change from the May result but the startling outcome is that Rebecca White leads Will Hodgman as preferred premier by the thumping margin of 48% to 37%.

Let's put that in the historic context drawn from other states.  It's very simple: preferred premier is an indicator that usually strongly favours incumbents.  When established state premiers trail as preferred leader in Newspoll (never mind by eleven points), they either lose the next election or are removed by their own party.  EMRS is not Newspoll, and it's possible its continued devotion to landline polling (which I strongly believe to be not fully randomised) has meant its results have become total rubbish.  But if that's not the case, the government should be rather worried.  The suggestion is that so far negative attacks on the new Opposition Leader have either not worked at all or even backfired.  

Opposition Leaders don't lead by eleven points just because people like them.  Historically this sort of imbalance happens when governments are in deep trouble or their leaders are unpopular, or both. Federal governments sometimes recover from it; state governments historically don't. The large lead for Rebecca White is probably also a sign that among the voters who EMRS flags as undecided, or as intending to vote for a minor candidate, there are probably a lot who are leaning towards Labor or likely to direct preferences Labor's way.  It should be noted, for contrast and a bit of sobrietry, that the recent ReachTEL had only a small White lead from a format that doesn't skew to incumbents, so perhaps this EMRS is an outlier.  I am also aware of an unpublished commissioned poll showing Hodgman with a small lead using similar question design to EMRS.

Reachtel: It's All About Lyons

Mercury ReachTEL Lib 43 ALP 32.9 Green 13.4 Other 10.7 (after redistributing "undecided")
Interpretation Lib 43 ALP 36.7 Green 10.7 Other 9.8
Most likely result right now based on this poll would be hung parliament (12-10-3) closely followed by narrow Liberal majority (13-10-2)
New aggregate of all polling: Liberal majority (13-10-2) with hung parliament (12-10-3) next most likely.

A Mercury ReachTEL of state voting intention is now out with a sample size of a whopping 2817 voters.  My initial comments on it will be very brief because I am playing in a chess tournament this weekend and also so that the Mercury get good commercial value for their polling data, which I expect can be found in full in the Sunday Tasmanian.  More detailed comments may be posted on Sunday night.  There was also a commissioned poll of Lyons this week - see Fishy Prospects In The Seat Of Lyons.

This new poll again presents a story that I have repeated so many times in state polling coverage over the last two years that presumably something entirely different will happen and it will all be wrong!  The overall picture of polling for some time has shown the Hodgman Government's majority hanging by a thread, given the virtually certain loss of a seat in Braddon and the likely loss of another in Franklin.  With the Greens struggling to hold their seat in Bass, the key question then is whether the Greens (or somebody) can knock off one of the three Liberal MPs in Lyons.  If that happens the majority goes, and it could be that the government goes with it.  There are a number of possible fourth-party/independent wildcards, but at this stage none of them are known to have their acts together.

EMRS: Both Majors Rebuild Following Labor Leader Change

EMRS: Lib 39 ALP 34 Green 15 Ind 7 PHON 3 Others 2
Interpretation: Lib 41 ALP 37 Green 12 PHON 3 all others 7
Liberals would probably just retain majority based on this poll

A very brief preliminary report on the EMRS state poll just released (http://www.emrs.com.au/pdfs/EMRS%20State%20Voting%20Intentions%20Report%20-%20May%202017.pdf)  See also the trend tracker at http://emrs.com.au/.

The poll shows a noticeable recovery by both major parties (the Liberals up four points and Labor up five) at the expense of the Greens, One Nation and the supposed "independent" vote (all down three), following both Labor's shift to Rebecca White and a tanking in the national One Nation vote. In other states, points that have come off One Nation have generally gone straight back to Labor, so the Liberals will be relieved if that turns out not to be the case down here.

The Greens' result may look OK, since it is higher than their 2014 election outcome, but EMRS has a long history of overestimating their vote by a few points, so they would probably go backwards in an election held "right now".  This isn't any surprise really - they were always going to struggle when Labor shifted to a young, female and relatively left-wing leader.  While the salmon farming issue may yet play out in the party's favour, they sorely lack both experienced MPs and the shiny new thing factor and may even have a fight on their hands in Franklin come election day.

EMRS: Liberals Crash, But Hodgman Still Clobbering Green

EMRS Feb 2017: Lib 35 ALP 29 Greens 19 Ind/Other 11 One Nation 6 
On these numbers a hung parliament would be inevitable (approx 11 Liberal, 10 Labor, 4 Green, though one more Liberal seat might fall to One Nation or the Greens)

EMRS Nov 2016: Lib 40 ALP 28 Green 18 Ind/Other 13 (One Nation not in readout)
On these numbers most likely result would have been a hung parliament (approx 12 Liberal, 10 Labor, 3 Green)

Current seat aggregate of all polls: Lib 12 ALP 10 Greens 3

Note: EMRS tends to skew to Greens and Others and against ALP.  No evidence on skew for or against One Nation is known.

--------------------------------------------------------------------------------------------------------

Once again, Tasmanian phone pollster EMRS has released two of its quarterly polls, for November and February, in a single release.  See also the trend tracker, which shows that the Liberal vote has been falling for four years now.

For the first time, One Nation has been included in the readout, and immediately the Hodgman Government has lost five points to 35%, its worst position of the term.  Even the Roy Morgan series, which was obviously skewed against the Government (and hasn't been seen since October) never had it below 37.

Not-A-Poll Results: Best And Worst Tasmanian Ministers

For amusement and interest, in the last couple of months I have been running two reader Not-A-Polls in the sidebar concerning Tasmania's current Liberal ministry.  As the usual disclaimer goes, these not-a-polls are completely unscientific and represent only the opinions of those site readers (or random ring-ins) who may have chosen to participate.  Polldaddy has more advanced protections against multiple voting than the native polls on the Blogger site that I used to use, but I suspect they could be routed around if anyone was truly determined.  Also, this kind of exercise is especially prone to a word-of-mouth stack, where someone tells a bunch of their friends who would not normally read this site to vote on it.

Indeed there seemed to be something of that sort going on in the final week when there were sudden large gains for both Will Hodgman as best and Guy Barnett as worst.

Anyway, the following are the results for the Best Minister poll (in order), the Worst Minister poll (in reverse order) and a final ranking based on net scores (best minus worst) with position difference (best minus worst, 9 points for best on each scale to 1 for worst) used as a tiebreaker.  Had I used position difference to rank the results with net scores as the tiebreaker, the final order would have been the same.

New Tasmanian State Poll: Rolling Comments

ReachTEL Liberal 45.6 Labor 30.9 Green 15.1 Other 8.4 (Undecided removed)
On raw numbers, it is a tossup whether Liberals would just retain majority (c. 13-10-2) or just lose it (c. 12-10-3)
Adjusted for house effects, Liberals would be likely to retain majority (13-10-2)

Introduction (15 Nov)

A new Tasmanian ReachTEL poll of state voting intention, with a large sample size, is about to be released by The Mercury.  As noted in the teaser, the poll points to the probable loss of two or three seats if the government were to face the music today.  A loss of two seats would leave the government with a majority of one while a loss of three would create a hung parliament.  This will be familiar territory for those who have followed my state polling coverage in the term, as my aggregated polling model has pointed to either 12 or 13 Liberal seats for a long time now.

Polling in Tasmania was inaccurate at the federal election, and has shown large pro-Liberal house effects at both the last two federal elections (but not at the 2014 state election) so there will always be some room for doubt about it.  Another important factor is the potential for a tactical bandwagon effect as seen in the 2006 election - if one party has a realistic chance of majority government and the other does not, voters may gravitate to that party.  While polling says the government's majority would be touch and go if an election were "held now", that assessment has very little predictive value because of this kind of strategic voting.

I have seen some of the results for the purposes of expert comment, but a recent business model change by The Mercury means I will be going about posting analysis of this poll in a slightly different manner.  As I understand it, many of the results will be released behind a paywall in the first instance and then published in the print edition the next day.  I won't be posting analysis of the results until they have appeared in the print edition, at least in basic form, or been freely reported.

As results are revealed over the next several days, in-depth coverage will be posted below.

EMRS: Liberals Rebound, But Still Shaky

EMRS August 2016: Liberal 41 Labor 31 Green 15 "Independent" 11 Others 2
Intepretation: Liberal 42.5 Labor 33.5 Green 12 Others 12
Seat projection on this poll: Liberals would be slightly favoured to just retain majority (approx 13-10-2, with 12-10-3 next most likely)
No seats are projected to fourth parties/independents as no prominent fourth parties/independents are yet known to be running

Aggregate of all recent polling 12-10-3 (no majority)


Another EMRS poll of state voting intentions is out.  Also see the useful trend tracker.  After dipping to its lowest level for many years in the July poll, the Hodgman Liberal government has rebounded to a position similar to that in the May poll.  This is consistent with the July poll result having been contaminated by the Liberals' woeful performance in Tasmania at the federal election, and not too much should be read into the four-point shift in this poll for that reason.

EMRS: Libs Could Have Copped A Whacking, But ...

EMRS Liberal 46 Labor 27 Green 18 Independent 8 Others 1
Interpretation (provisional) Liberal 47 Labor 31 Green 15 Others 7
Result of poll if election "held now": Probable Liberal majority government (13-9-3)
Aggregate of all state polling: Liberal majority government (13-8-4)

The new EMRS poll of Tasmanian voting intentions is out (PDF link) and the results are surprisingly harmless for the Hodgman Liberal government.  Given that the gloss has come off the federal Turnbull bounce which probably helped the Liberals to such a good result last time, there were many reasons to suspect this poll could be a shocker.

In the last few months the state has been beseiged by bushfires, drought, floods, traffic congestion in Hobart, energy issues and talk of a crisis as a result of a still-unfixed fault in the Basslink power cable, and even an outbreak of mass oyster death.  While most of these are just "natural disasters" that shouldn't hurt governments (and might even help them if their response was good), responses to both the energy and traffic issues have raised the question of preparedness.  While the preparedness question applies to previous governments at least as much as this one, and goes to the question of whether government generally is all that good these days, one might expect the current government to cop some blowback from it all.  Perhaps in the energy case we'll need to wait and see whether it actually affects consumers first.

How Bad Is Bryan Green's Rating?

Last week I reported on the EMRS poll which has shown a probably Turnbull-led resurgence for Tasmania's Hodgman Liberal state government.  One figure has dominated discussion of the poll in the subsequent week:

19%

19% is the preferred premier rating of Labor Opposition Leader Bryan Green (compared with Will Hodgman's 56).  I often rail here against the media overuse of preferred-leader stats to spin a yarn, and against polls that poll preferred-leader scores but don't also poll and release approval ratings.  I even have a piece here declaring such scores to be rubbish.  They're not totally meaningless, but they're messy indicators that are often biased to incumbents, they lag behind changes in approval rating, and they don't have a very good predictive record.

Part of the problem is that a preferred-leader score is a comparative indicator, so it's impossible to discuss what it says about one leader without thinking about what it says about another.  Does a big lead for an incumbent Premier say that voters really like the Premier and don't mind the Opposition Leader, or does it say that voters mildly like the Premier and can't stand his opponent?  EMRS have been polling the answers to these questions, but unfortunately they haven't been releasing the results.

As Matt Smith observes (in a notable piece that suggests Labor are disheartened and just going through the motions) numbers like this can spell a lot of trouble for a leader, and can ignite leadership speculation.  We shouldn't overstate the "trouble" angle; some state leaders have dragged on for years with miserable polling, but there have also been cases interstate where just one poll like this has been game over.
