​

Legislation creating semi-open primaries in Maine went into effect in May 2022.  The bill allows people who are not registered with either party to participate in primary voting beginning in 2024.

​

In presidential, state, and congressional primaries, voters must affiliate with a party to vote in their primary, but unaffiliated voters may affiliate with a party on election day. Affiliated voters wishing to update their affiliation must do so at least 15 days before an election. You can update your affiliation 3 months after the date of your last party change.
