With nearly 60 million ballots already cast, everyone interested in the presidential election is trying to figure out where the race stands.
Despite so many votes having been cast, it is hard to know what it means. Many more people have yet to vote, and exactly how many there will be or how they will split are unknown. But there is one measure in the early voting data that could be more suggestive about the final results: the number of new voters who have already voted.
And an NBC News Decision Desk analysis of state voter data shows that as of Oct. 30, there are signs of an influx of new female Democratic voters in Pennsylvania and new male Republican voters in Arizona, two of the most important swing states.
The early votes of new voters — voters who did not show up in 2020 — are of particular interest because they are votes that could change what happens in 2024 relative to the last presidential election. (Who voted in 2020 and doesn’t show up this time is also important, but it’s impossible to know before Election Day.)
Already, the number of new voters in many of the seven closest battleground states exceeds the 2020 margin between President Joe Biden and former President Donald Trump. In Pennsylvania, for example, Biden beat Trump in 2020 by 80,555 votes. This year, over 100,000 new voters have already cast ballots in Pennsylvania, with more to come.
We can’t know how these new voters voted, but looking at who they are can provide hints about how 2024 might swing relative to 2020. Party registration does not perfectly predict a voter’s choice, but new voters who choose to register as Democrats are more likely to vote for Vice President Kamala Harris than not, and new voters who register as Republicans are more likely to vote for Trump. As a result, in the swing states where voters can formally register for a party (Arizona, Nevada, North Carolina and Pennsylvania), the new voters affiliated with a party may provide some hints about the 2024 election.
(In Georgia, Michigan and Wisconsin, where voters don’t officially register with a party, the best we can do to predict the partisanship of new voters relies on local voting patterns and demographics — data that can be quite noisy and sometimes wrong.)
The gender of new voters in these states is also public data, shining light on the relationship between gender and party registration among new voters amid an election hinging on a number of political issues related to gender, such as abortion. (Some states also offer a “nonbinary” or “other” option on their voter registration forms, with a small number of voters using that so far.)
Female Democrats dominate new voter numbers from Pennsylvania
Let’s start in Pennsylvania — not only because it is thought to be the closest state according to the polls, but also because the number of new voters who have cast ballots there has already exceeded the 2020 margin. If everyone from 2020 voted for the same candidate again, these new voters would decide the race.
The data out of Pennsylvania shows large differences in the number of votes cast by new voters, both by party registration and by gender. More new voters are registered Democrats than Republicans, and new female voters are driving this partisan gap. The new male voters are only slightly more likely to be Democrats than Republicans, but among new female voters, Democrats outnumber Republicans nearly 2 to 1.
