Kamala Harris maintains narrow lead in key states in US presidential race

The United States presidential election will be held on November 5. In analyst Nate Silver’s aggregate[1] of national polls, Democrat Kamala Harris leads Republican Donald Trump by 49.3–46.2, a slight gain for Trump since last Monday[2], when Harris led Trump by 49.3–46.0.
Joe Biden’s final position before his withdrawal as Democratic candidate on July 21 was a national poll deficit against Trump of 45.2–41.2.
In economic data, the US added 254,000 jobs in September[3] and the unemployment rate slid 0.1% to 4.1%. The unemployment rate had peaked at 4.3% in July.
The US president isn’t elected by the national popular vote, but by the Electoral College, in which each state receives electoral votes equal to its federal House seats (population based) and senators (always two). Almost all states award their electoral votes as winner-takes-all, and it takes 270 electoral votes to win (out of 538 total).
Relative to the national popular vote, the Electoral College is biased to Trump, with Harris needing at least a two-point popular vote win to be the Electoral College favourite in Silver’s model.
In the key states, Harris remains ahead in Silver’s poll aggregates by one to two points in Pennsylvania (19 electoral votes), Michigan (15), Wisconsin (ten) and Nevada (six). If Harris wins these four states, she probably wins the Electoral College[4] by at least 276–262. Trump leads by 0.5 points in North Carolina (16 electoral votes), one point in Georgia (16) and 1.2 points in Arizona (11).

In Silver’s model, Harris has a 56% chance to win the Electoral College, unchanged since last Monday’s article. The FiveThirtyEight model[6] was more favourable to Harris in September, but now gives her a 55% chance to win. It’s close to a 50–50 probability for either candidate, but Harris remains a slight favourite.
There are still more than four weeks to go until the election, so there’s time for the polls to change and for one candidate to have a decisive Electoral College advantage on election day. Or the polls could be understating either Harris or Trump, in which case the candidate that benefits from the poll error could have a decisive win.
Thumping lead for LNP in Queensland
The Queensland state election is on October 26. A Freshwater poll[7] for The Financial Review, conducted September 26–29 from a sample of 1,067, gave the Liberal National Party (LNP) a 56–44 lead, a five-point gain for the LNP since the previous Freshwater poll in July 2023.
Primary votes were 43% LNP (up three), 30% Labor (down four), 12% Greens (up one), 8% One Nation (up one) and 7% for all Others (down one).
Labor Premier Steven Miles had a net approval of -5, while LNP leader David Crisafulli had a +15 net approval. Crisafulli led Miles by 46–38 as preferred premier.
The poll asked about the federal leaders’ Queensland ratings, with Anthony Albanese at net -17, while Peter Dutton was at net zero. Queensland is a Coalition-friendly state at federal elections relative to the national results.
Federal Newspoll quarterly data
On September 30, The Australian released aggregate data for the four Newspolls[9] taken from July to September, which had a combined sample size of 5,035. The Poll Bludger[10] said the Coalition led in New South Wales by 51–49, unchanged on the June quarter.
In Victoria, Labor led by 52–48, a two-point gain for the Coalition. In Queensland, the Coalition led by an unchanged 54–46. In Western Australia, Labor led by an unchanged 52–48. In South Australia, Labor led by 54–46, a one-point gain for Labor.
The Poll Bludger’s BludgerTrack data[11] shows the results by educational attainment. In the September quarter, Labor led by 53–47 among university-educated people, a one-point gain for Labor. With TAFE-educated people, there was a 50–50 tie, a one-point gain for the Coalition. Those with no tertiary education favoured the Coalition by 51–49, a one-point gain for the Coalition.
Coalition gains lead in Morgan poll
A national Morgan poll[12], conducted September 23–29 from a sample of 1,668, gave the Coalition a 51–49 lead, a 1.5-point gain for the Coalition since the September 16–22 Morgan poll.
Primary votes were 38% Coalition (up 0.5), 30% Labor (down two), 13.5% Greens (up one), 4.5% One Nation (down 0.5), 9.5% independents (steady) and 4.5% others (up one).
The headline figure uses respondent preferences. But if preferences were assigned using the 2022 election flows, Labor led by 51.5–48.5, a 0.5-point gain for the Coalition. There was an unusually large gap last week between the two measures.
Resolve poll on Middle East conflict
Voting intentions have not yet been released from a national Resolve poll[13] for Nine newspapers that was conducted October 1–5 from a sample of 1,606. Regarding the political response in Australia to the Middle East conflict, 22% thought Dutton and the Liberals had responded best, 18% Albanese and Labor and 6% Adam Bandt and the Greens, while 55% said none had responded best or were unsure.
On Australia’s actions, 23% thought we should voice in-principle support for Israel, 12% Gaza and 65% both or none. On accepting refugees, 52% don’t want any refugees accepted, 24% would accept refugees from either Israel or Gaza, 13% Gaza only and 11% Israel only.
