Middlesex County District Attorney

If AG Tom Reilly runs for governor, then there's a good chance that Middlesex County DA Martha Coakley will run for DA (just as Reilly did when AG Scott Harshbarger ran for governor). If so, who would run for Coakley's seat? SCO rounds up the early contenders on the Democratic side. Many are state legislators, so there'd be a whole cascading effect.
