Poll wrap: Labor maintains its lead in Newspoll, while One Nation drops; NSW upper house finalised

With five weeks until the May 18 election, this week's Newspoll, conducted April 11-14 from a sample of 1,700 people, gave Labor a 52-48 lead, unchanged since last week. Primary votes were 39% Coalition (up one), 39% Labor (up two), 9% Greens (steady) and 4% One Nation (down two) - One Nation's lowest primary vote since November 2016.

While the two-party figure was unchanged, this poll is better for Labor than last week's Newspoll, with Labor gaining two points in primary votes from One Nation's drop. If we assess this poll as total right-wing vs total left-wing vote, the left (Labor and Greens) gained two points to stand at 48%, while the right (Coalition and One Nation) lost one point to fall to 43%. Analyst Kevin Bonham said this Newspoll was probably rounded towards the Coalition.

One Nation's drop is likely the result of increased polarisation between the major parties. If One Nation had been affected by the NRA donations scandal, it would have shown up in last week's polls.

Nominations for the federal election will be declared on April 24. It is unlikely that One Nation will contest the vast majority of lower house seats. Polling conducted after April 24 is likely to greatly reduce One Nation's vote as they will no longer be an option for most Australians in the lower house. This reduction of One Nation's vote may assist the Coalition on primary votes.

In the Newspoll, 45% of respondents were satisfied with Prime Minister Scott Morrison's performance (steady), and 44% were dissatisfied (up one), for a net approval of +1. Labor leader Bill Shorten's net approval was steady at -14. Morrison led Shorten by an unchanged 46-35 as better PM.

Since Malcolm Turnbull was ousted as prime minister in August 2018, the Coalition has recovered from a 56-44 deficit in Newspoll to 52-48 this week, due partly to the time that's passed since the spill and partly to the relative popularity of Morrison.

Now that the election campaign is formally under way, some attention will shift to the opposition's policies and proposals. The danger for Labor is the Coalition can scare voters about its economic policies, but the potential reward is that Labor can appeal to voters who are frustrated by the Coalition's perceived inaction on climate change and low wage growth.

Large difference in voting intentions by age group

Every three months, Newspoll aggregates all the polls it conducted from that time period to get voting intention breakdowns by state, age, gender and region (the five capital cities vs the rest of Australia). For January to March, the overall result was 53-47 to Labor, a point better for Labor than the last two Newspolls.

This three-month Newspoll showed a large difference in voting intentions by age group. Among those aged 18-34, Labor had 46% of the primary vote, the Coalition 28%, the Greens 14% and One Nation 4%. Among those aged 35-49, it was Labor 39%, Coalition 35%, Greens 9% and One Nation 7%. And among those aged 50 or over, the Coalition had 44%, Labor 35%, One Nation 6% and Greens 5%.

It is still important to poll well with this oldest demographic. According to the 2016 census, those aged 18-34 represent 30.3% of the eligible voting age population and those aged 35-49 represent 26.0%. The share of the voting-age population aged 50 or over, however, is 43.7%.

Results by gender were similar. Men gave Labor 40% of the primary vote, the Coalition 37%, the Greens 7% and One Nation 6%. With women, Labor had 39%, the Coalition 37%, the Greens 10% and One Nation 6%. After preferences, Labor would be doing about one point better with women than men.

The best source for state voting intentions is The Poll Bludger's BludgerTrack. Perhaps reflecting the Coalition's victory in the recent NSW election, federal Labor's lead over the Coalition in that state has been reduced to just 50.1-49.9 from about 54-46 in the last few weeks. This is about a 0.6% swing in Labor's favour from 2016.

Labor has maintained a larger lead in most other states, however. In Victoria, Labor leads by 55.1-44.9, a 3.2% swing to Labor since 2016. In Queensland, Labor leads by 52.0-48.0, a 6.1% swing to Labor. In SA, Labor leads by 55.7-44.3, a 3.4% swing to Labor.

In WA, the Coalition still leads by 51.0-49.0, but this is a 3.6% swing in Labor's favour from 2016.

Nationally, BludgerTrack gives Labor a 52.5-47.5 lead, a 2.8% swing to Labor.

One Nation wins two seats in the NSW upper house

In the March 23 NSW election, 21 members of the upper house were elected by statewide proportional representation, with a quota of 1/22 of the vote, or 4.55%.

The Coalition won 7.66 quotas, Labor 6.53, the Greens 2.14, One Nation 1.52, the Shooters, Fishers & Farmers 1.22, the Christian Democrats 0.50, the Liberal Democrats 0.48, Animal Justice 0.43 and Keep Sydney Open 0.40.

The Coalition was certain to win an eighth seat, and Labor and One Nation were best placed for two other seats. On preferences, Animal Justice overtook the Liberal Democrats, Christian Democrats and One Nation to win the second-to-last seat, with One Nation's second candidate, Rod Roberts, defeating the Christian Democrats for the final seat.

It is the first time since 1981 that the Christian Democrats have failed to win a seat in the NSW upper house. David Leyonhjelm, who resigned from the Senate to run as the lead Liberal Democrat candidate in NSW, did not win.

The Coalition now holds 17 of the 42 total upper house seats (down three), Labor 14 (up two), the Greens four (down one), the Shooters two (steady), One Nation two (up two), Animal Justice two (up one) and the Christian Democrats one (down one). One Green member, Justin Field, resigned from the party, and is now an independent.

Overall, the right now holds 22 of the 42 seats. On legislation opposed by the left-wing parties, the Coalition will require support from One Nation, the Shooters and Christian Democrats.

Brexit likely delayed until at least October 31

The European Union leaders have decided to delay Brexit until at least October 31. Without a majority for any plausible Brexit option, the House of Commons could only vote to delay Brexit to prevent a no-deal departure from the EU, but this delay will likely not appeal to the general public or "leave" voters.

Two new polls have the Conservatives slumping to just 28-29% of the UK vote, 4-7 points behind Labour.
