I think there is a really good chance Trump will win Pennsylvania. Mostly because Trump has enlisted a large army of volunteers to watch every polling place in Pennsylvania (the New Black Panthers can’t be outside the polling places anymore!) and because I think even western Pennsylvania will be high majority in favor of Trump.
I am in Western PA. I am seeing Trump yard signs and even huge Trump flags on homes in solidly Democrat blue collar neighborhoods.
I have seen two Hillary signs. That ties her with Gary Johnson locally.
