Over 136,000 Mainers have already cast their ballots in the upcoming general election.

According to Maine Public, data from the Secretary of State's Office shows that most of these votes have come from registered Democrats.

Democrats have submitted roughly 52% of ballots, compared to just 20% from Republicans and unenrolled voters, commonly referred to as independents.

No-excuse absentee voting and early in-person voting are available to Mainers through Oct. 29.

Absentee ballots may be requested online here, but your local town hall must receive completed ballots by 8 p.m. on Election Day, Nov. 3.

Maine voters may also request an absentee ballot in person with a paper application.

Completed absentee ballots must be returned to your local town hall. Most municipalities have a secure drop box outside the building where voters can deposit their ballots.

A complete list of municipal office hours and drop box locations is available here.

Mainers may also vote in person at their local polling place on Election Day, Nov. 3. Opening and closing times vary by location.

Maine citizens who have not yet registered to vote may do so until polls close on Election Day.

Voters unsure of their registration status can check with their local municipal clerk's office.
