Dems clearly have a higher ceiling and floor than the GOP does in PA. I can't remember the last time the GOP has won a statewide race by double digits (Specter in 2004?), but the Dems have a bunch of times. GOP wins tend to be narrow, as Toomey only won by <2 points twice and Trump by <1 point. Ironically, Corbett's 9 point in 2010 stands out as one of the best GOP performances.
1998: Tom Ridge won re-election as governor by 57-31.......and that's with the Constitution Party's nominee Peg Luksik receiving over 10%. Arlen Specter was re-elected by 61-35. Since then, yes, only Specter's 2004 win exceeded a 10% margin in a Senate/Gubernatorial race.
