Voters trekking to the polls around the state Tuesday, March 3, will be tasked with voting for their choice of presidential candidate in Maine’s primary. The 129th Maine Legislature enacted a Presidential Primary law in 2019 (PL 2019, Chapter 445), for the purpose of allowing Maine voters to designate their preference for the nomination of their party’s candidate.

The Green Independent Party chose not to participate in the Presidential Primary election but will hold party caucuses for voting for the Presidential candidate and conducting other party-building activities. 

Below is the alphabetical listing of candidates appearing on the ballot for Maine voters, with a notation of the state in which they claim full-time residence. Not all candidates filed to appear on the Maine ballot, or dropped out of the race before filing to appear on the Maine ballot.
