If Trump can cut into the black vote in PA or there is low turnout in Philly, he has a real shot. Of course there is voter fraud in Philly where they manufacture the votes needed to win. Hard to see Hillary running stronger than Obama in PA and Trump will do better than Romney getting the blue collar white vote.
If Trump wins PA, he wins the election. He or Pence should be there more. Without PA, he needs either Colorado or Wisconsin assuming that he can’t win Michigan or VA.
