To vote in a primary election or participate in a caucus, you must be enrolled in a political party.  If you are unenrolled, you may enroll in a party at any time, including caucus day or election day.  However, if you are changing parties, you must do so at least 15 days before that party’s caucus or primary.  You may file a request to change or withdraw party enrollment only after three months of enrollment in one of the three recognized political parties in Maine – Democratic, Green Independent, or Republican.  Please note that although some unenrolled candidates and voters choose to designate themselves as “Independent,” there is no Independent Party in Maine.

For the March 3, 2020 Presidential Primary, the deadline to change parties is February 14.  If you are unenrolled, you may enroll in a party at any time, including election day.
