Editor’s note (July 21st): Joe Biden has stepped down as the Democratic nominee. We have paused our analysis until we have sufficient polling data about his successor. Read more about what will come next.
The race between Joe Biden and Donald Trump is very close. Over the first three months of 2024 the candidates were never more than three points apart in our average of national polls, with Mr Trump narrowly ahead for most of that time. That is new for Mr Trump: in his two previous presidential campaigns he never led a general-election polling average for a single day. More worrying still for Mr Biden, Mr Trump is ahead in several of the swing states that he lost in 2020. The outcome in half a dozen states— Arizona, Georgia, Michigan, Nevada, Pennsylvania and Wisconsin—is likely to prove decisive. A small but critical slice of voters who plumped for Mr Biden back then are now telling pollsters that they plan to defect. Who are they?
To find out, we built a statistical model to assess how a hypothetical voter might cast a ballot, based on their demographic traits. Our data come from YouGov, an online pollster, which every week surveys over a thousand people about their demographic profile, voting history and voting intentions. We combined all its survey results since January 2023 to get a detailed portrait of Americans’ voting preferences. Use the drop-down menus below to plug in any combination of attributes—age, sex, religion and more—to construct a hypothetical American and see our estimate of their vote. Or press shuffle to see a voter at random. Our model will continuously update to incorporate each week’s YouGov survey.

The voters propelling Mr Trump’s polling renaissance might come as a surprise. While white voters’ preferences have changed little since 2020, racial minorities—historically the bedrock of Democratic support—have lurched away from Mr Biden. Mr Trump has also sharply cut into his successor’s advantage among young voters, another core Democratic group. Mr Biden will hope these once-loyal Democrats return to the fold once the campaign heats up.

Race is often cited as the central cleavage in American politics, yet the single most powerful predictor of voting intention is religion. A model that knows nothing save for respondents’ religious affiliations can correctly identify their preferred candidate 62% of the time, compared with 59% for race. Of Mormons and evangelical voters, 73% say they support Mr Trump. This compares with just 13% of avowed atheists.

Rather than the sharp realignment that took place in 2016 and 2020, when Mr Trump attracted working-class white voters while shedding college-educated ones, the voters swinging in either direction this year are more alike: they tend to be young; black or Hispanic; and live in cities. This suggests they have looser party alliances and pay less attention to politics.
So both sides will think they can win as the election approaches. And you can use this tool to explore the type of voter—a 40-year-old high-school-educated black man from rural Georgia, say—who might just swing it.■
