Polls are open in New Hampshire, where voters in both parties are casting their ballots in the first-in-the-nation primary to decide who should be president.

Former President Donald Trump, the Republican frontrunner, is facing off against former U.N. Ambassador Nikki Haley, his lone remaining challenger for the 2024 GOP nomination after Florida Gov. Ron DeSantis dropped out of the race.

On the Democratic side, President Biden is running virtually unchallenged for reelection — but he’s also not on the ballot in New Hampshire. (Here’s why.)

Yahoo News will have live coverage of the primary throughout the day and night as the results come in. Get updates in the blog below.
