Now here's a question...as Pennsylvania goes, building an electoral coalition for the Reps...are SW PA and the philly burbs almost mutually exclusive?
Not against Obama, they aren't. I could conceivably see Romney overperforming in the Philly burbs and still holding down Pennsyltucky by the virtue that he isn't Obama. In otherwords, following the Toomey model makes sense. Although I'd expect Romney to do better in Fayette, Greene and Washington County. Obama's approval ratings there are horrendous, even compared to his weak election result.
