Term limits

The Maine legislature is one of 15 state legislatures with term limits. Voters enacted the Maine Term Limits Act in 1993. That initiative said that Maine senators are subject to term limits of no more than four two-year terms, or a total of eight years.

The first year that the term limits enacted in 1993 impacted the ability of incumbents to run for office was in 1996.

Vacancies

If there is a vacancy in the senate, a special election must be held to fill the vacant seat. The Governor must call for an election and allow all political committees representing the vacant seat to set all deadlines. The person elected to the seat serves for the remainder of the unexpired term.
