Judy Adams, an environmental activist from Circle Pines, Minn., announced Monday she will seek the Democratic endorsement to run for Congress in Minnesota's 6th District.
Adams is a political rookie, having never run for public office, but said her experience with activism helped her understand the process.
Adams said she's unlikely to run in the DFL primary if she can't get the party endorsement.
Last week, radio host and former gubernatorial candidate Tom Emmer announced his candidacy for Bachmann's seat. Emmer, a Republican, said he wants to follow in Bachmann's footsteps by fighting "the ever-growing size of government."
