Under state law, those seeking to change party affiliation must file an application in the town where they reside at least 15 days before Maine’s presidential caucus.
The republican caucuses are scheduled for February 1st, 2nd and 3rd.
The democratic caucus will be held February 10th.
Mainers who want to switch to that party have until January 26th to register.
Independent voters can register the same day as the caucus as either a democrat or republican.
