Post-budget poll wrap: Labor has equal best Newspoll budget result, gains in Ipsos, but trails in Longman

This week's Newspoll, conducted May 10-13 from a sample of 1,730, gave Labor a 51-49 lead, unchanged from three weeks ago. Primary votes were 39% Coalition (up one), 38% Labor (up one), 9% Greens (steady) and 6% One Nation (down one).

This Newspoll is Malcolm Turnbull's 32nd successive loss as PM, two more than Tony Abbott. However, the past two have been narrow losses.

The total vote for Labor and the Greens was up one point to 47%, while the total for the Coalition and One Nation was steady at 45%. The gain for the left would normally result in a gain after preferences, but rounding probably helped the Coalition again.

39% (up three) were satisfied with Turnbull, and 50% (down three) were dissatisfied, for a net approval of -11, Turnbull's highest net approval since the final pre-election Newspoll in July 2016. Bill Shorten's net approval was down two points to -22. Turnbull led Shorten as better PM by 46-32; this is Turnbull's clearest better PM lead since February.

Newspoll asks three questions after every budget: whether the budget was good or bad for the economy, good or bad for you personally, and whether the opposition would have delivered a better budget.

The best news for Labor was on the third question, where it only trailed by seven points, equal to their deficit after the badly perceived 2014 budget. According to The Poll Bludger, Labor trailed by more during all of the Howard government's budgets.

This budget was seen as good for the economy by 41-26, and good for you personally by 29-27. The Poll Bludger says it is fifth out of 31 budgets covered by Newspoll on personal impact, but only slightly above average on the economy.

Turnbull led Shorten by 48-31 on best to handle the economy (51-31 in December 2017). Treasurer Scott Morrison led his shadow Chris Bowen 38-31 on best economic manager. By 51-28, voters thought Labor should support the government's seven-year tax cut package.

Turnbull has delivered a well-received budget, while Shorten's credibility took a hit after four Labor MPs were kicked out over the citizenship fiasco.

Voters were not sympathetic to politicians who held dual citizenships. By 51-38, they thought such politicians should be disqualified from federal parliament (44-43 in August). By 46-44, voters would oppose a referendum to change the Constitution to allow dual citizens to become MPs.

A key question is whether Turnbull's ratings bounce will be sustained. The PM's net approval and the government's two party vote are strongly correlated, so the Coalition should do better if Turnbull's ratings are good. Past ratings spikes for Turnbull have not been sustained.

While people on low incomes receive a tax cut, it will not be implemented by withholding less tax from pay packets. Instead, people will need to wait until they file their tax returns after July 2019 to receive their lump sum tax offsets. As the next federal election is very likely to be held by May 2019, this appears to be a political mistake.

In last week's Essential, 39% thought the Australian economy good and 24% poor. While Australia ran large trade surpluses in the first three months of this year, the domestic economy is not looking as good as it did in 2017 - see my personal website for more.

Ipsos: 54-46 to Labor (53-47 respondent allocated)

An Ipsos poll for the Fairfax papers, conducted May 9-12 from a sample of 1,200, gave Labor a 54-46 lead by 2016 election preferences, a two-point gain for Labor since early April. Primary votes were 37% Labor (up three), 36% Coalition (steady), 11% Greens (down one) and 5% One Nation (down three).

Newspoll is no longer using last-election preferences, so it seems better to compare Ipsos' respondent allocated preferences with Newspoll, not the last election preferences. By respondent allocated preferences, Ipsos was 53-47 to Labor, a three-point gain for Labor.

Ipsos is bouncier than Newspoll, and the Greens' support is higher. If you compare Ipsos' respondent allocated two party vote with Newspoll, the difference is diminished.

Turnbull had a 51-39 approval rating (47-43 in April). This is Turnbull's best rating in Ipsos since April 2016; Ipsos gives Turnbull his strongest ratings of any pollster. Shorten's net approval was up three points to -12. Turnbull led Shorten by 52-32 (52-31 in April).

By 39-33, voters thought the budget was fair (42-39 after the 2017 budget). By 38-25, voters thought they would be better off, the highest "better off" figure in Nielsen/Ipsos history since 2006. However by 57-37, voters thought the government should have used its extra revenue to pay off debt, rather than cutting taxes.

Queensland Galaxy: 52-48 to federal Coalition, 53-47 to state Labor

A Queensland Galaxy poll, conducted May 9-10 from a sample of 900 for The Courier Mail, gave the federal Coalition a 52-48 lead, unchanged since February, but a 2% swing to Labor since the 2016 election. Primary votes were 40% Coalition (down one), 33% Labor (up one), 10% Greens (steady) and 10% One Nation (up one). Primary vote changes would normally imply a gain for Labor, but this was lost in the rounding.

By 39-33, Queenslanders thought the budget was good for them personally, rather than bad. By 39-28, they thought the budget would be good for Queensland.

The state politics questions gave Queensland Labor a 53-47 lead, a one-point gain for Labor since February. Primary votes were 38% Labor (up one), 35% LNP (down one), 12% One Nation (up two) and 10% Greens (steady).

Premier Annastacia Palaszczuk had a 46-38 approval rating (44-38 previously). Opposition Leader Deb Frecklington had a 31-28 approval rating (29-25). Palaszczuk led Frecklington as better Premier 47-27 (42-31).

Longman ReachTEL: 53-47 to LNP

The Longman byelection is one of five that will be held soon. A ReachTEL poll, conducted May 10 from a sample of 1,280 for the left-wing Australia Institute, gave the LNP a 53-47 lead, about a 4% swing to the LNP since the 2016 election. Primary votes were 36.7% LNP, 32.5% Labor, 15.1% One Nation and 4.9% Greens.

ReachTEL is using respondent allocated preferences. The two party vote in this poll looks reasonable assuming One Nation preferences flow to the LNP.

National polls and the Queensland Galaxy poll show swings to Labor compared with the 2016 election. It would be highly unusual for a seat to swing so strongly to the Coalition when other polling shows a swing to Labor. In the past, seat polls have been far less reliable than national and state-wide polls.

In better byelection news for Labor, the Western Australian Liberals will not contest either Perth or Fremantle. Fremantle has a 7.5% margin with an incumbent recontesting, but Labor only holds Perth by a 3.3% margin with no incumbent.

Essential: 52-48 to Labor

This week's Essential, conducted May 10-13 from a sample of 1,033, gave Labor a 52-48 lead, a one-point gain for the Coalition since last week. Primary votes were 38% Coalition (steady), 36% Labor (down one), 10% Greens (steady) and 7% One Nation (up one).

By 44-28, voters approved of the budget overall. 22% thought the tax cuts would make a difference to their household. 39% supported the tax cuts, with 30% wanting more spending on schools and hospitals and 18% preferring a reduction in government debt.

By 44-40, voters disagreed with giving higher income people larger tax cuts. By 79-14, voters agreed that those earning $200,000 should pay a higher tax rate than those earning $41,000.
