Polls close at 7:30 p.m. Eastern time. In the 2022 state primaries, first results were reported 8 minutes later, and the last update of the night was at 12:52 a.m. Eastern time with 99 percent of votes reported. Tuesday’s results could be reported later because of a new law that requires officials to wait until polls close to tabulate early votes.

Voters affiliated with a party were eligible to cast a ballot in that party’s primary, though unaffiliated voters could choose to vote in any party’s election. The state offered an early in-person voting period, and no excuse was required to vote absentee. Voters could return absentee ballots by mail or in person as long as they were received by the close of polls.

An option to vote “no preference” appeared on the presidential ballot. In last week’s primary in Michigan, more than 13 percent of Democrats voted “uncommitted” as part of a protest of President Biden’s policies toward Israel and the war in Gaza.

North Carolina is one of five states on Tuesday holding presidential primaries as well as its state primary, which will include races for state and congressional offices.
