Maine does not permit online voter registration. There is no cut-off date for registering to vote in person at the town office or city hall. If voting by mail or through a voter registration drive, fill out a voter registration application, print it, sign it and mail it to the voter registrar in the county of residence. For information about early voting, check out: https://www.maine.gov/sos/cec/elec/voter-info/earlyvoting.html . Your vote is valuable to the state and makes a difference!
