Poll wrap: Coalition's record Newspoll losing streak, and Rebekha Sharkie has large lead in Mayo

This week's Newspoll, conducted June 14-17 from a sample of 1,660, gave Labor a 52-48 lead, unchanged since three weeks ago. Primary votes were 38% Coalition (steady), 38% Labor (steady), 10% Greens (up one) and 6% One Nation (down two).

This Newspoll is Malcolm Turnbull's 34th consecutive loss as prime minister, four ahead of Tony Abbott. According to analyst Kevin Bonham, this is the worst Newspoll losing streak for a government, with Turnbull and the Coalition now one ahead of Julia Gillard's 33 successive losses as PM.

Prior to July 2015, Newspoll was conducted by landline live phone polling with samples of about 1,100. Since July 2015, Newspoll has been administered by Galaxy Research, using robopolling and online methods with samples of about 1,700. The new Newspoll is much less volatile than the old Newspoll, so trailing parties have far less chance of getting lucky with an outlier 50-50 poll.

In this Newspoll, the total vote for Labor and the Greens was up one to 48%, and the total vote for the Coalition and One Nation was down two to 44%. This matches a late March Newspoll as the highest vote for the left-of-centre parties this term. These changes would normally give Labor a two party gain, but it is likely the previous Newspoll was rounded up to 52%, and that this one has been rounded down.

40% were satisfied with Turnbull's performance (up one), and 50% were dissatisfied (also up one), for a net approval of -10. Bill Shorten's net approval was down one point to -22. Turnbull continued to lead Shorten by a large 46-31 as better PM (47-30 previously).

Turnbull's ratings improvement has been sustained since the budget. It is likely he is benefiting from the tax cuts in the next financial year. Recently, hard-right Coalition MPs have not had as much influence on government policy as they used to, and Turnbull is probably benefiting from this.

While Turnbull's ratings improved, I believe the greater focus on the government's tax policies and the publicity regarding Barnaby Joyce are holding back the Coalition's vote. One Nation probably slumped owing to the split between Pauline Hanson and Brian Burston, who is now a senator for Clive Palmer's new United Australia Party.

Both Newspoll and Essential's fieldwork was mostly conducted before the federal Liberal council passed a motion to privatise the ABC on Saturday. This vote is likely to be embarrassing for Turnbull and Coalition ministers.

The Australian has been campaigning against the Australian National University's refusal to allow a Western civilisation course. Most voters would have heard nothing about this issue. It is not surprising that, when given a question skewed in favour of the Western civilisation course, voters backed it by a 66-19 margin.

Essential: 52-48 to Labor

This week's Essential poll, conducted June 14-17 from a sample of just over 1,000, gave Labor a 52-48 lead, a two-point gain for the Coalition since last fortnight. Primary votes were 38% Coalition (up two) and 35% Labor (down two). Tables have not yet been published, so The Poll Bludger's report is the best for domestic issues.

79% supported the first stage of the income tax cuts that are introduced in the next financial year, but only 37% supported the third stage, which is scheduled to be phased in from 2024 – these tax cuts would flatten the tax scales. Support and opposition to the company tax cuts were tied at 39% each.

From Peter Lewis in The Guardian, 35% thought the agreement between US President Donald Trump and North Korean dictator Kim Jong-un would make the world safer, 8% less safe, and 41% thought it would make no difference.

Despite Trump's presidency, 50% consider it very important for Australia to have a close relationship with the US, followed by the UK at 47% and China at 39%. Russia at 17% and Saudi Arabia at 14% are at the bottom of this table.

By 54-11, voters had a favourable view of New Zealand PM Jacinda Ardern, followed by Canadian PM Justin Trudeau (54-14), German Chancellor Angela Merkel (43-18), French President Emmanuel Macron (42-15) and UK PM Theresa May (42-19). Trump had an unfavourable 64-22 rating, Russian President Vladimir Putin 56-19 unfavourable and Kim Jong-un 68-9.

Two Mayo polls give Rebekha Sharkie 58-42 leads over Georgina Downer

On July 28, Mayo is one of five seats up for federal byelections. The incumbent, Centre Alliance's Rebekha Sharkie, was forced to resign over the dual citizenship fiasco, but will recontest. The Liberal candidate is Georgina Downer, daughter of Alexander Downer, who held Mayo from 1984 to 2008.

A ReachTEL poll for the left-wing Australia Institute and a Galaxy poll for The Advertiser both gave Sharkie a 58-42 lead over Downer. Primary votes in Galaxy were 44% Sharkie, 37% Downer, 11% Labor and 6% Greens. In ReachTEL, primary votes were 41.4% Sharkie, 35.5% Downer, 11.1% Greens and 8.2% Labor.

These poll results represent a 3% swing to Sharkie in Mayo compared to the 2016 election. The ReachTEL poll was conducted June 5 from a sample of 1,031, and the Galaxy poll June 7 from a sample of 515.

In the Galaxy poll, 62% had a positive view of Sharkie and just 10% a negative view. In contrast, 31% had a positive view of Downer and 41% a negative view.

The Centre Alliance was Nick Xenophon's former party, and the expectation was that Sharkie would follow Xenophon down. However, it appears that she has built up a strong profile in Mayo that is independent of Xenophon's appeal. It is likely Sharkie will defy the collapse of her party to retain Mayo.

It could be perceived that Downer thinks she should have the seat because it was her father's seat. Other weaknesses for Downer are her membership of the hard-right Institute of Public Affairs, and her absence from Mayo for the last 20 years.

The Australia Institute ReachTEL has left-skewed additional questions. Question 2, regarding company tax cuts, gave unpopular examples of large companies — banks, mining companies and supermarkets. It then offered three options for company tax rates (increased, kept the same or decreased), with only one unfavourable to The Australia Institute's left-wing agenda.

Three weeks ago, The Australian had a right-skewed company tax cut question in Newspoll, but left-wing organisations often do the same thing, though their profile is far lower than Newspoll.

In brief: Darling Range (WA) byelection, Conservatives win in Ontario and Colombia

A byelection for the Western Australian state seat of Darling Range will be held on Saturday. At the March 2017 state election, Labor won Darling Range by 55.8–44.2 against the Liberals, a massive 18.9% swing to Labor from the 2013 election. However, Labor member Barry Urban was forced to resign over allegations of fraudulent behaviour. A ReachTEL poll for The West Australian gave Labor a 54-46 lead in Darling Range.

At the June 7 Ontario provincial election, the Conservatives won 76 of the 124 seats, the left-wing NDP 40, the centre-left Liberals seven and the Greens one. The Liberals had governed Ontario for the last 15 years. The Conservatives won just 40.5% of the popular vote, with 33.6% NDP, 19.6% Liberals and 4.6% Greens. First Past the Post, which is used in all federal and provincial Canadian elections, greatly benefited the Conservatives with the left vote split. You can read more at my personal website.

At the Colombian presidential runoff election held on Sunday, conservative Iván Duque Márquez defeated the left-wing Gustavo Petro by a 54.0-41.8 margin. Duque opposes the 2016 peace deal between the government and guerrilla fighters.
