Would Wood Waste Waste The Seat Of Franklin?

There's a law called Betteridge's Law that says any headline that ends in a question mark can be answered with the word "no".  This article is certainly no exception.


Regrowth after logging and burning, showing burnt "wood waste" in the foreground.

It's a polling trope as old as the hills.  Some issue that virtually no-one was hitherto believed to know about or care about is suddenly the subject of startling polling revealing that Party X needs to support it or brace itself for double-digit vote losses.  It's a concept that thrives on the unhealthy symbiosis between activists/lobbyists and journalists (the journalist gets a free story complete with new polling while the activist/lobbyist gets their press release put out as news, usually with no outside scrutiny of the polling involved).  And it seldom if ever amounts to the proverbial hill of beans.

The latest in this unfortunate genre has been an article (Bill Shorten faces a Tasmania Wood Waste Wipeout - Google for article title if paywalled) declaring that polling shows Labor headed for a dire fate in Tasmania if it opposes the inclusion of wood waste in the Renewable Energy Target.  This is based on a ReachTEL poll conducted for the Australian Forest Products Association (AFPA).

What Would Happen If Jacqui Lambie Resigned From The Senate?

This piece is brought to you by the Department of Absurd Hypotheticals, but there are a couple of reasons for it.

Firstly, as the Palmer United Party Senator for Tasmania now seems to be embarrassing her country, her state and (to the limited extent possible) herself and her party on a more or less weekly basis, quite a few voters wish she would quit.  Lambie has recently called for the resignation of Defence Minister David Johnston, and a natural response for many was to call for Lambie to get out of politics instead.  

It's no more at this stage than wishful thinking.  Lambie comes from a difficult financial background and a likely six years as a Senator will set her up nicely for the rest of her life.  There are also some issues she seems to care about (for better or worse, varying by case) and she probably thinks she can make a difference to them in her role.  So I definitely don't think she's going anywhere - though whether she stays under the PUP umbrella remains to be seen. 

However, those who are thinking of calling for Lambie to quit the office to which she is so unsuited may want to know: if she did resign from the Senate, what would happen?

Tas Labor Push-Polling? Not As Such, But ...

Wirrah Award For Fishy Polling (image source)


In the final week of the Tasmanian state election campaign, the Tasmanian ALP has been accused of push-polling.  This follows the apparent leaking, by forces unknown, of an internal Labor UMR poll.

I have also obtained the contentious poll, which was conducted by telephone interviews with a sample size of 300 voters in each of Lyons and Franklin.  The Liberal Party needs to win three seats in at least one of these electorates, and is very likely to do so in Lyons, but lineball in Franklin.

The questions for the two electorates, conducted 5-6 March, appear in a results section entitled "Messaging".  Each question has the opening question "Does the following statement make you more or less likely to vote Labor in the state election or does it make no difference?"  The statements then are:

Tasmanian Lower House: 25 or 35 Seats?

This article has been updated for elections from 2014 to 2025. Scroll down to the bottom for these updates.

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


Advance summary (pre-2014 version):

1.  The possibility of restoring the old 35-seat system in the Tasmanian House of Assembly is currently being discussed ahead of a motion to be moved by the Greens.

2. Looking at past election results and current polling, the 35-seat system is slightly more proportionally accurate, while the 25-seat system is slightly more prone to "over-represent" the major parties in comparison to vote share.

3. However, precise proportional representation in the Tasmanian context can easily be argued to be overrated anyway.

4. Of the elections considered (and a 2014 projection based on current polling), only in the case of 1998 did the choice of systems determine the election result.

5. Majority government is slightly more likely on average with 25 seats than with 35 seats, but in many scenarios the number of seats makes no real difference to its chances.

6. Strategic considerations favour the Greens supporting an increase in the number of seats and the Liberals opposing it, while for the Labor Party there are arguments on both sides.

7. The view that the Greens could plausibly win more seats than Labor at the next election if the 25-seat system is retained is not consistent with current polling.

8. It is not correct to blame too many problems in Tasmanian politics on the 25-seat system since politics under the 35-seat system was also very turbulent and crisis-prone during its last two decades.

Silly Lilleys: Is Wayne Swan Losing His Seat? - Updated

Note: this is an older article that has been updated a number of times.  Everything below the line is not very relevant to the upcoming election following the change in Prime Minister, and with Swan now on the backbench, the answer for many will be "who cares?"

Update: 31 August: The great poetic irony that was supposed to occur if Kevin Rudd's resurrection as PM saved Swan's seat is again in danger, with the seat jittery based on seat margin polling, reports of internal polling and now a public poll.  A JWS Research robopoll reports a 53.8:46.2 result in this seat in favour of the Coalition, although it should be noted that seat polls have been delivering generally nasty stuff for Labor compared to national polling.  By no means a surefire indicator of defeat for Swan, but it is better not to poll such numbers than to poll them.

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

Advance summary of original article:


1. An opinion poll has been reported as showing the Treasurer, Wayne Swan, headed for defeat in his seat of Lilley.

2. While this finding may yet prove correct, there are many reasons to treat the finding cautiously.

3. These reasons include the likely closeness of the poll once preferences are considered, the poll's small sample size, the non-naming of the key candidates, and the poll being commissioned by an interest group.

4. With all these reasons considered, the poll provides no clear insight into the likely fate of Swan's seat, which is already known to be marginal and at substantial risk.

5. Polls commissioned by interest groups should be treated with much caution, because even if they are impeccably designed, groups may decide whether or not to release such polls depending on whether they like the results.

March Update: (More details at bottom of article.) Some similar comments apply to a second Lilley poll in early March, except that the key candidates are named, the sample size is larger, and this is the second released poll now claiming this result, so the level of overall doubt about the findings is lower.

The primary figures provided would produce a closer 2PP result than claimed.  The second poll's finding that a change to Rudd would result in an increase of about eight points is unreliable as polls in which voters anticipate how they would respond to hypothetical situations are generally not to be trusted.  Nonetheless a return to Kevin Rudd is capable of making a big difference to the chances of this seat being held. 

June 3 Update: Things are looking dodgier for the Treasurer now, considering the dire state of the national 2PP and the recent Galaxy Queensland poll which showed a state swing large enough (but only just) for the Treasurer to lose if uniformly applied.  An "internal poll" has been reported as showing him on a primary of just 28%, however the usual caveats apply to internal polling that has not been released in full detail and that may be being released selectively or be methodically suspect.

June 11 Update: However we now (see here) see the first publicly released polling result (Fairfax-commissioned ReachTEL) in which the Treasurer has been in front (53:47), although the lead in this sample is within its margin of error based on a sample size of 600.  This does not necessarily mean Swan has turned anything around; it is quite possible that all the published polls are within the neighbourhood of an actual picture in which the fight for the seat is very close.  Full details of the poll are yet to be released.
