Romney will not win PA under any circumstances. My state is a case in point on why the RNC’s strategy to “appeal to moderates” won’t work. The libs in the Philly area will stick with Obama and Romney won’t turn out the base in Carville’s “T” in Pennsylvania. These are blue collar people with classic American values, not just mindless “haters” of the current President. A millionaire Mormon from Massachusetts has no appeal to them. They’re independent thinkers and don’t just vote party line. The candidate has to appeal to them. Turnout was down in the primary from 2008 despite McCain already having all the delegates he needed in 2008. McCain was a better crossover candidate for PA than Romney and he lost by 10 points. OH and FL were much closer losses for McCain so Romney has a chance there.
A Republican hasn't won PA since G.H.W. Bush in '88. Not really sure why they call it a swing state. It's pretty solidly blue when it comes to electing a president.
