Poll wrap: Phelps slumps to third in Wentworth; Trump's ratings up after fight over Kavanaugh

The Wentworth byelection will be held on October 20. A ReachTEL poll for independent Licia Heath’s campaign, conducted September 27 from a sample of 727, gave the Liberals’ Dave Sharma 40.6% of the primary vote, Labor’s Tim Murray 19.5%, independent Kerryn Phelps 16.9%, Heath 9.4%, the Greens 6.2%, all Others 1.8% and 5.6% were undecided.

According to The Poll Bludger, if undecided voters were excluded, primary votes would be 43.0% Sharma, 20.7% Murray, 17.9% Phelps, 10.0% Heath and 6.6% Greens. Compared to a September 17 ReachTEL poll for GetUp!, which you can read about on my personal website, primary vote changes were Sharma up 3.7%, Murray up 3.3%, Phelps down 4.8%, Heath up 5.6% and Greens down 6.0%. Phelps fell from second behind Sharma to third behind Murray and Sharma.

Between the two ReachTEL polls, Phelps announced on September 21 that she would recommend preferences to the Liberals ahead of Labor, backflipping on her previous position of putting the Liberals last. It is likely this caused her slump.

While more likely/less likely to vote a certain way questions always overstate the impact of an issue, it is nevertheless bad for Phelps that 50% of her own voters said they were less likely to vote for her as a result of the preference decision.

This ReachTEL poll was released by the Heath campaign as it showed her gaining ground. Heath appears to have gained from the Greens, and the endorsement of Sydney Mayor Clover Moore could further benefit her.

Despite the primary vote gain for Sharma, he led Murray by just 51-49 on a two candidate basis, a one-point gain for Murray since the September 17 ReachTEL. The Poll Bludger estimated Murray would need over three-quarters of all independent and minor party preferences to come this close to Sharma.

At the 2016 election, Malcolm Turnbull won 62.3% of the primary vote in Wentworth. While the Liberals’ primary vote in this poll is about 19% below Turnbull, it is recovering to a winning position.

Trump, Republicans gain in fight over Kavanaugh Supreme Court confirmation

On July 9, Trump nominated hard-right judge Brett Kavanaugh to replace the retiring centre-right judge Anthony Kennedy. The right currently has a 5-4 Supreme Court majority, but Kennedy and John Roberts have occasionally voted with the left. If Kavanaugh is confirmed by the Senate, it will give the right a clearer Supreme Court majority. Supreme Court judges are lifetime appointments.

Although Kavanaugh is a polarising figure, he looked very likely to be confirmed by the narrow 51-49 Republican majority Senate until recent sexual assault allegations occurred. Since September 16, three women have publicly accused Kavanaugh of sexual assault when he was a high school or university student.

On September 27, both Kavanaugh and his first accuser, Christine Blasey Ford, testified before the Senate Judiciary Committee. On September 28, without calling additional accusers, the Committee favourably reported Kavanaugh by an 11-10 majority, with all 11 Republicans – all men – voting in favour.

However, after pressure from two Republican senators, the full Senate confirmation vote was delayed for a week to allow an FBI investigation. The Senate received the FBI’s findings on Thursday, and the investigation did not corroborate Ford. Democrats have labelled the report a “whitewash”, but it appears to have satisfied the doubting Republican senators, and Kavanaugh is very likely to be confirmed.

Since the sexual assault allegations against Kavanaugh began, Trump’s ratings in the FiveThirtyEight poll aggregate have recovered to about a 42% approval rating, from 40% in mid-September. Democrats’ position in the race for Congress has deteriorated to a 7.7 point lead, down from 9.1 points in mid-September.

Midterm elections for all of the US House and 35 of the 100 Senators will be held on November 6. Owing to natural clustering of Democratic votes and Republican gerrymandering, Democrats probably need to win the House popular vote by six to seven points to take control.

While the House map is difficult for Democrats, the Senate is far worse. Democrats are defending 26 Senate seats and Republicans just nine, Five of the states Democrats are defending voted for Trump in 2016 by at least 18 points. Two polls this week in one of those big Trump states, North Dakota, gave Republicans double digit leads over the Democratic incumbent.

The FiveThirtyEight forecast models give Democrats a 74% chance of gaining control of the House, but just a 22% chance in the Senate.

Republican gains in the polls are likely due to polarisation over Kavanaugh. In a recent Quinnipiac University national poll, voters did not think Kavanaugh should be confirmed – by a net six-point margin – but Trump’s handling of Kavanaugh was at -7 net approval. Democrats led Republicans by seven points, and Trump’s overall net approval was -12. Kavanaugh was more unpopular than in the previous Quinnipiac poll, but Trump and Republicans were more popular.

The hope for Democrats is that once the Kavanaugh issue is resolved, they can refocus attention on issues such as healthcare and the Robert Mueller investigation into Trump’s ties with Russia. However, the strong US economy assists Trump and the Republicans.

In brief: contest between left and far right in Brazil, conservative breakthrough win in Quebec, Canada

The Brazil presidential election will be held in two rounds, on October 7 and 28. If no candidate wins over 50% in the October 7 first round, the top two proceed to a runoff.

The left-wing Workers’ Party has won the last four presidential elections from 2002 to 2014, but incumbent President Dilma Rousseff was impeached in August 2016, and replaced by conservative Vice President Michel Temer.

Workers’ Party candidate Fernando Haddad and far-right candidate Jair Bolsonaro are virtually certain to advance to the runoff. Bolsonaro has made sympathetic comments about Brazil’s 1964-85 military dictatorship. Runoff polling shows a close contest.

In the Canadian province of Quebec, a conservative party won an election for the first time since 1966.
