The Tasmanian election will be held on Saturday. A ReachTEL poll, conducted for The Mercury on February 22 from a large sample of more than 3,100, gave the Liberals 46.4% of the vote, Labor 31.1%, the Greens 12.1%, the Jacqui Lambie Network (JLN) 5.2%, others 2.0%, and 3.3% were undecided.

When undecideds are excluded, the Liberals have 48.0%, Labor 32.2%, the Greens 12.5%, and JLN 5.4%.

Tasmania uses the Hare-Clark system, with five five-member electorates. A quota is one-sixth of the vote, or 16.7%. Sample sizes for each electorate in ReachTEL were 620-650. The Liberals had well over 50% in Bass and Braddon, and 49.6% in Lyons, implying they would win three of the five seats in each.

In Franklin, the Liberals had 42.6%, easily enough for two seats. In Denison, the Liberals had 33.8%, just enough for two seats.

On the stated figures, the most likely overall seat outcome is 13 or 14 Liberals out of 25, eight-to-ten Labor, and two or three Greens. So, the Liberals should win a majority.

Like other Tasmanian polls, ReachTEL has in the past skewed to the Greens and against Labor. At the last two federal elections, ReachTEL skewed to the Liberals in Tasmania, though it skewed against the Liberals at the 2014 state election.

Adjusting for ReachTEL’s skew, Tasmanian analyst Kevin Bonham thinks the most likely outcome is 13 Liberals, ten Labor, and two Greens. The next two most likely outcomes are 13 Liberals, 11 Labor, one Green; and 12 Liberals, 11 Labor, two Greens.

I do not think opposition to Labor’s anti-pokies policy caused the swing to the Liberals during the campaign. The most important factor was probably that many Tasmanians detest the Greens, and will vote for the major party most likely to win a majority. In 2006, Labor easily won an election that had appeared likely to result in a hung parliament.

The Greens’ vote of 12.5% in this poll is below the 13.7% they won at the 2014 election, and it could be lower given ReachTEL’s pro-Greens skew. It is likely the Greens are doing badly because Labor, under Rebecca White’s leadership, has become more left-wing, so the Greens are having trouble differentiating themselves from Labor.

Incumbent Will Hodgman led White by 51.8-48.2 on ReachTEL’s forced choice better premier question. Labor’s pokies policy was supported against the Liberals’ policy by a 57-43 margin.

ReachTEL 54-46 to federal Labor

A Sky News ReachTEL, conducted February 22 – the day before Barnaby Joyce resigned – had federal Labor leading by 54-46, a two-point gain for Labor since late January. Primary votes were 37% Labor (up one), 33% Coalition (down one), 11% Greens (up one), and 7% One Nation (down one). The remaining 12% probably included some undecided voters.

ReachTEL is using respondent-allocated preferences, which have been better for the Coalition than previous election preferences, as One Nation preferences are flowing to the Coalition at a greater rate than the 50-50 flow at the 2016 election. By last election preferences, Bonham calculates this poll was about 55.5-44.5 to Labor. This makes it one of the worst polls for the Coalition this term.

Despite the blowout in the Labor margin, Malcolm Turnbull continued to lead Bill Shorten by 53-47 in ReachTEL’s forced choice better prime minister question (54-46 in January). Although the Joyce affair appears to have damaged the Coalition, Turnbull is not being blamed.

Last week’s Newspoll, conducted February 15-18 from a sample of 1,630, gave Labor a 53-47 lead, a one-point gain for Labor. Primary votes were 37% Labor (steady), 36% Coalition (down two), 10% Greens (steady), and 8% One Nation (up three). This was Turnbull’s 27th successive Newspoll loss, three short of Tony Abbott.

The overall Labor/Green vote in this Newspoll was 47%; the left vote has been stuck at 47% in Newspoll since August. Despite the Joyce affair, the overall Coalition/One Nation vote was up one point to 44%.

Turnbull’s ratings were 34% satisfied, 54% dissatisfied (37-50 previously). Shorten’s ratings were the same as Turnbull’s, and Turnbull led Shorten 40-33 as better prime minister (45-31 previously).

A total of 65% thought Joyce should resign as deputy prime minister, while only 23% thought he should stay. By 64-25, voters supported a ban on politicians having sexual relations with their staff. By 57-32, voters supported Shorten’s policy to give Indigenous people a voice to federal parliament.

As long as Republicans hold Congress, no chance of real US gun control

After the recent Florida high school gun massacre, there has been a renewed push for US gun control. However, as I wrote following the Las Vegas massacre in October, meaningful gun control will not happen under Donald Trump and the current Republican-controlled Congress.

The Florida state legislature, which Republicans control 76-40, defeated a motion to debate a ban on assault weapons by 71-36, even as students from the affected school looked on. Instead, it passed a motion declaring pornography a public health risk.

Trump’s ratings are currently 39.1% approve, 55.6% disapprove, in the FiveThirtyEight poll aggregate. Before the gun massacre, Trump’s approval had risen to 41.5% owing to perceptions of an improving US economy; for several weeks, Trump’s approval was at least 40%.

Democrats lead by 47.0-38.8 in the race for Congress. Before the massacre, the Democrats’ lead had fallen to 6.4 points. All 435 US House of Representatives seats will be up for election in November, and also one-third of the 100 senators. Democrats probably need a mid-to-high single-digit popular vote margin to win control of the House of Representatives.

Italian election: March 4

The Italian election will be held on March 4. 37% of both chambers of the Italian parliament will be elected by first past the post, and the remainder by proportional representation.

Italy imposes a blackout on polling during the final two weeks of election campaigns. The last polls were published on or before February 16.

In the final pre-blackout polls, the centre-right coalition was in the high 30s, with the centre-left coalition and the populist left Five Star Movement trailing with about 27% each. A left-wing breakaway from the centre-left had about 6%.

Even though the overall left vote is about 60%, the right could win a majority owing to the first-past-the-post seats.

The centre-right coalition includes former prime minister Silvio Berlusconi’s old party (Forza Italia). Although Berlusconi is banned from contesting elections, he could be the power behind the throne if his coalition wins a majority in both chambers.
