A former state legislator and a current city councilor are looking to fill an open seat representing Biddeford in the Maine Legislature. John Eder, a former Green party state representative, and City Councilor Victoria Foley will square off in the Democratic primary to fill the seat being vacated by Martin Grohman, who is running for Congress. The winner of the June 12 primary will run against unenrolled candidates Wesley Charles Davis and Matthew Lauzon in the general election for the District 12 seat, which represents Biddeford.
