Dixville Notch, NH has returned the first results in the 2024 US election. The town voted at midnight and only six ballots were cast, so tallying the results didn't take long. In the presidential race the results were evenly split, with 3 votes each for Kamala Harris and Donald Trump.

Edit: AP has now removed the blue squares in New Hampshire from their map.
That's standard practice everywhere else in the US. New Hampshire has this thing about being first, though. They have the earliest presidential primary as well. Releasing early results for this one tiny town is a minor publicity gimmick that shouldn't have any impact on the overall election. Even the rest of New Hampshire's towns will wait until Tuesday evening to report their results.
