Primary elections

Wyoming has closed primaries: only voters registered with a party can vote in that party’s primary. Party changes must be made well before the primary; Wyoming no longer allows switching parties on primary day.

Voter ID

Wyoming requires an ID to vote in person, and some non-photo IDs are accepted. If you don’t have acceptable ID, you can vote a provisional ballot, but you must take extra steps after Election Day for it to count.

Early voting

Starts: Twenty-eight days before election (in-person absentee). Ends: Day before election. Locations and hours are set locally.

Voting by mail

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