PA-06: A GOPer Eyes The Seat—Is This A Sign That Gerlach’s Gone?
According to CQ, Republican state representative Curt Schroder has filed with the FEC for Pennsylvania’s 6th Congressional District. Schroder’s move could just be a “just in case” action, but it could also be a sign that the longtime legislative veteran is convinced that Rep. Jim Gerlach (R) is leaving the House, for either a run for Governor or as a moderate alternative to Pat Toomey for the U.S. Senate. For the Democrats, former Inquirer editorial board member Doug Pike is already planning a bid.
