Because the Maine Legislature changed the state to a primary state in 2019, the Maine Democratic Party (MDP) is holding municipal caucuses Sunday, March 8, although party-enrolled members will have already voted for their presidential preference in the Tuesday, March 3, primary election.

The Democratic caucuses, organized by the MDP in partnership with local committees, will be an opportunity for Maine Democrats to elect their local party leaders and, based on their presidential preferences, delegates to the state convention.

While the presidential primary will determine how Maine Democrats will distribute their national delegates, the municipal caucuses on March 8 and the state party convention May 29-31 will determine who the delegates will be attending the Democratic National Convention July 13-16 in Milwaukee.

All registered Democrats can participate in the municipal caucuses, including 17-year-olds who will be 18 by November 3 who register to vote and enroll as a Democrat. Individuals who are unaffiliated or unenrolled can register as Democrats up to caucus day, including at the caucus. Detailed information on the primary and the municipal caucuses, including recommended advance caucus check-in, is available at
