Cumberland County Sheriff Mark Dion announced this morning that he plans to run for the Maine House of Representatives in the fall, seeking to represent North Deering and West Falmouth.

Dion will seek to become the Democratic party’s candidate for the House District 113 seat at a party caucus in Portland on Sunday. Dion is not running for reelection as sheriff.

Charles C.S. Burns, of Summit Street in Portland was the Republican nominee but withdrew his candidacy June 22. Party officials say a replacement candidate will be chosen this weekend.

The seat had been held by Democrat Joan F. Cohen who was nominated by Democrats during the June 8 primary, but she withdrew her candidacy on July 6, according to state records.

State law permits the parties to nominate replacement candidates if the nominee withdraws within the proscribed time period.
