HARRISBURG (AP) – Democrats will avoid a primary fight in the race for Republican Congressman Jim Gerlach‘s seat. Chester County businessman Mike Parrish said he’s dropping out and supporting fellow Democrat, Dr. Manan Trivedi. That leaves Trivedi unopposed for the Democratic nomination in the May 20 primary. Lawyer Ryan Costello, a Chester County commissioner, is unopposed for the GOP nomination. Gerlach’s district takes in parts of Chester, Berks, Lebanon, and Montgomery Counties.
