Poll wrap: Palmer's party has good support in Newspoll seat polls, but is it realistic?

With 23 days to go until the May 18 election, Newspoll had seat polls of Herbert, Lindsay, Deakin and Pearce. All four polls were conducted April 20 from samples of 500-620. Clive Palmer’s United Australia Party (UAP) had the support of 5% in Deakin, 7% in Lindsay, 8% in Pearce and 14% in Herbert.

Seat polls are notoriously unreliable. In addition, the UAP has clearly been added to the party readout in these seats. Pollsters regularly ask for Labor, the Coalition, the Greens and One Nation. All other voters are grouped as “Others”, although a follow-up question can be asked – if Other, which other?

The strongest indication that UAP support is overstated in these seat polls is that the all Others vote is unrealistically low in three of the four seats polled. In Herbert, Pearce and Deakin, all Others are at just 2%, while they are 8% in Lindsay. It is likely that many of those who will vote for Others at the election said they would vote for the UAP as that party was in the readout.

Herbert was tied at 59-50, unchanged from the 2016 election. In Lindsay, Labor was ahead by 51-49, also unchanged. The Liberals led by 51-49 in Deakin, but this was a solid swing to Labor from 56.4-43.6 to the Liberals at the 2016 election. In Pearce, there was a 50-50 tie (53.6-46.4 to Liberals at the 2016 election).

Primary votes in Herbert were 31% LNP, 29% Labor, 14% UAP, 10% Katter’s Australian Party, 9% One Nation and 5% Greens. In Deakin, primary votes were 46% Liberals, 39% Labor, 8% Greens and 5% UAP. In Pearce, primary votes were 40% Liberals, 36% Labor, 8% Greens, 8% UAP and 6% One Nation. In Lindsay, primary votes were 41% Liberals, 40% Labor, 7% UAP and 4% Greens.

Relative to the national swing, Labor is expected to struggle in the Townsville-based seat of Herbert due to the Adani coal mine issue. In Lindsay, the retirement of Labor MP Emma Husar in controversial circumstances may have made it vulnerable.

Bad ReachTEL seat polls for Labor in Bass and Corangamite

There were two ReachTEL seat polls conducted last week from samples of 780-850. In the Labor-held Tasmanian seat of Bass, the Liberals had a 54-46 lead. In the Victorian seat of Corangamite, which is on no margin following a redistribution, the Liberals led by 52-48. The Bass poll was conducted for the Australian Forest Products Association, and the Corangamite poll for The Geelong Advertiser.

Bass and Tasmania have an older demographic than Australia overall. I wrote last week that, according to Newspoll data, those aged 50 or over are best for the Coalition. Corangamite also has an older demographic than the country overall.

Labor won Bass by 56.1-43.9 at the 2016 election, a 10.1% swing to Labor. But at the 2013 election, Bass was the best of the five Tasmanian seats for the Liberals, and this also occurred at the March 2018 state election. Labor’s big 2016 swing may have been caused by the unpopularity of hard-right Liberal MP Andrew Nikolic. In the July 2018 federal byelections, Labor had an underwhelming victory in Bass’s neigbouring seat, Braddon.

While seat polls are unreliable, the Corangamite and Bass polls are evidence that, as reported by The Poll Bludger originally from The Australian Financial Review, Scott Morrison appears to have a greater appeal to blue-collar and outer suburban voters than Malcolm Turnbull, and this has helped the Coalition in seats like Bass and Corangamite.

One Nation to contest 59 of the 151 House seats

Nominations for the election were declared this week. Labor, the Coalition, the Greens and the UAP will contest all 151 House seats. One Nation will contest 59 seats, with Fraser Anning’s Conservative National Party running in 48 seats, Animal Justice in 46 and the Christian Democrats in 42.

Until now, national pollsters have assumed One Nation was running in all seats for their polls. With One Nation only running in 39% of seats, most pollsters will reduce their national vote. This reduction may assist the Coalition on primary votes.

In the Senate, a quota for election is one-seventh of the vote, or 14.3%. Labor, the Greens and the Coalition are likely to be in the mix for the final seats in every state. It is possible that the small right-wing parties, such as Anning’s party, the UAP, the Australian Conservatives and Christian Democrats, could cause seats that should go to the right to go to the left instead if they do not tightly preference each other, One Nation and the Coalition.

Voters are told to number six boxes above the line for a formal vote, though only one number is actually required. At the NSW state election, left-wing micro-party voters preferenced more than right-wing micro-party voters, resulting in Animal Justice easily winning the final upper house seat.

At the federal election, it will be clear that left-wing micro-party supporters need to preference Labor and the Greens in their top six. It will be clear for right-wing micro supporters to preference the Coalition in the top six, but it is not likely to be clear which other right-wing party to preference.
