President Romney carried Pennsylvania easily, so Trump should have no issue /sarc
November 9th will a day of anger for Trump supporters. They might even riot in the streets.
Trump doesn't even need PA to win. If Hillary loses it however, the election is over.
(And seriously, when's the last time you seen Republicans riot. Liberals, on the other hand...)
Whatever helps you sleep at night. Trump won't win, because Satan isn't that powerful. The white supremacists will be out in the street trying to beat up every non-white person in sight when Trump loses, because they are already sending out threats on social media of putting people in ovens.
