Pennsylvania is losing one seat and it will be a Democrat one since Republicans run things here.
The old Jack Murtha district gets cut and boundaries are redrawn in the remaining 18 districts.
The new lines may help the GOP gain district (the 4th).
The party in charge after the census in each state does the gerrymandering.
Pennsylvania: Yeah, but I wouldn’t trust that Gleason guy with the GOP’s best interests in PA.
