Deadline for voters to change party affiliation before 2024 presidential primary is Oct. 6

CONCORD —  Voters have until Friday, Oct. 6, to change their party affiliation before voting in the 2024 presidential primary election, according to New Hampshire Secretary of State David M. Scanlan and Attorney General John M. Formella.

New Hampshire law permits only undeclared voters to choose in which primary election they vote. Otherwise, voters are eligible to vote only in the primary election for the political party with which they are affiliated.

Voters are affiliated with a political party when they declare an affiliation during voter registration, or when, as an undeclared voter, they vote in a political party’s primary. Unless the voter changes their political party affiliation after voting and before the next primary, the voter is limited by law to voting on the ballot for that same political party.

The secretary of state will notice the date of the New Hampshire presidential primary this fall. 

Voters can verify their affiliation through the secretary of state’s voter information look-up website, available by visiting app.sos.nh.gov.

Voters who wish to change their party affiliation may complete a change of party affiliation form at their town or city clerk’s office no later than Oct. 6, or attend the session of the Supervisors of the Checklist for their town, 7-7:30 p.m. on Oct. 6, to change their affiliation with the supervisors.
