Labor very likely to win WA election as One Nation slumps

The West Australian election will be held today. Polls close at 6pm local time (9pm Melbourne time). All three polls taken in the last week give Labor a 54-46 lead, which would represent an 11 point swing to Labor since the 2013 election. If this polling is accurate, Labor leads the combined Liberal/National total on primary votes. Here is the WA final poll table.

WA final polls.

The last Newspoll was taken in late January. Primary votes in this Newspoll were Labor 41% (up 3), Liberals 32% (up 2), Nationals 5% (steady) One Nation 8% (down 5) and Greens 7% (down 2). 34% (up 2) were satisfied with Premier Colin Barnett’s performance, and 57% (steady) were dissatisfied, for a net approval of -23. Opposition leader Mark McGowan had a net approval of +5, down 7 points. 54% thought Labor would win, with 27% backing the Liberals.

The last ReachTEL was taken for Fairfax on 27 February. After excluding 3.5% undecided, this ReachTEL has primary votes of Labor 41.8% (up 6.6), Liberals 33.9% (down 0.7), Nationals 6.0% (down 0.8), One Nation 6.8% (down 1.7) and Greens 6.5% (down 4.2). 61% thought the Liberals should not have entered a preference deal with One Nation, with only 22% in favour.

The only Galaxy poll since the last election was published last Sunday. It had primary votes of Labor 40%, Liberals 31%, Nationals 5%, One Nation 9% and Greens 8%.

On better Premier, McGowan led Barnett 45-37 in Newspoll, 56.5-43.5 in ReachTEL and 46-33 in Galaxy.

Much of Labor’s strong primary vote is coming at the expense of the Greens. Greens preferences help Labor in two party terms, so Labor will not do as well from preferences with a low Green primary.

It appears that the preference deal between the Liberals and One Nation has damaged both parties. From a peak of 12-13%, One Nation’s vote has slumped to 7-9%. The Liberals started the campaign behind, and this deal was an attempt to win One Nation lower house preferences. It is now likely that the Liberals will lose by a greater margin than if they had avoided this deal.

There may be shy One Nation voters, but neither ReachTEL nor Newspoll use live phone interviews. ReachTEL is a robopollster, while Newspoll uses robopolling and online panel methods.

Tasmanian EMRS poll: Liberals slump to 35%

A Tasmanian EMRS poll, conducted 1-4 March from a sample of 1000, has the Liberals on 35% (down 5 since November), Labor on 29% (up 1), the Greens on 19% (up 1), Independents on 10% (down 1) and One Nation on 6%.

Kevin Bonham says that EMRS skews to the Greens and Independents and against Labor. He interprets this poll as having primaries of 37% Liberal, 33% Labor, 16% Greens and 6% One Nation. Under Tasmania’s Hare Clark system, this poll would result in a hung Parliament with the Greens holding the balance of power; Bonham thinks 11 Liberals, 10 Labor, 4 Greens the most likely result.

No approval ratings are provided, but Premier Will Hodgman has a massive 52-20 lead over Labor’s Bryan Green as better Premier. Although better Premier is skewed in favour of the incumbent, the lead should not be this huge on a poll that would result in a Labor/Greens parliamentary majority. It is likely that Green’s lack of popularity is driving this disparity.
