Donald Trump is eyeing a second term, Joe Biden is down and out, Kamala Harris has rejuvenated the base. Can the Democrats win? Or is Trump stronger than he appears? Welcome to the New Statesman’s election forecast for the 2024 US election.
Our model will provide near daily projections of vote share estimates for each US state using a variety of poll and demographic data.
For much of 2024, Joe Biden lagged behind Trump in the polls. Trump unusually found himself ahead of the incumbent - and the televised debate between the pair in June only hardened this dynamic. It put Trump in reach of key states like Virginia, New Hampshire and Minnesota.
But Biden's decision to pull out has changed a lot. The Democrat base has rallied behind Harris though it is unclear how sustainable the current burst of energy is.
The election is likely to come down to the wire in seven states: Pennsylvania, Wisconsin, Michigan, Nevada, Arizona, Georgia, and the wild-card contest, North Carolina. Biden won six of these in 2020, but Trump has eked out leads in all of them for sustained periods this year.
The New Statesman's model is a probability model. Polls have error margins and in some of these key states pollsters have historically performed poorly. But, analysts have learnt from their mistakes too: namely the calamitous miscalculations during the 2016 Hillary Clinton campaign.
A healthy model ought to factor for all of this. While pollsters claim they have improved their methodology, healthy scepticism wouldn't go amiss. After 2016, for instance, the industry claimed they would alter their samples and surveys. But in 2020 the Trump vote was once again underestimated in key swing states.
In 2020 our model forecast that Trump had a one-in-ten chance of clinging on to the White House. Had our model run in 2016 the numbers would have said Trump had a one-in-three chance. Pollsters claim they have corrected for underestimating the Trump base since these elections. But there's a risk they have also overcorrected.
Here are the probabilities of a Kamala Harris win, state-to-state.
