Primary elections

New Mexico has semi-closed primaries: voters registered with a party vote in that party’s primary, and unaffiliated voters may choose one party’s primary.

Voter ID

New Mexico does not require most voters to show an ID document to vote in person; election workers confirm identity in other ways, such as checking a signature or personal information. First-time voters who registered by mail may need to show ID under federal law.

Early voting

Starts: Twenty-eight days before an election at a clerk’s office; on the third Saturday before an election for alternate locations. Ends: Saturday before election. Locations and hours are set locally.

Voting by mail

Any New Mexico voter can request an absentee/mail ballot. No excuse is needed.
