If Trump wins PA it simplifies things a lot in terms of stringing together enough electoral votes. If PA is called for Biden Ill have a pretty stressful night as the rest of the upper Midwest comes in.
Except Trump is ahead of where he was there in 2016.
PA is probably not going to be called on election day.
AZ + NC + MI can negate PA and make it irrelevant. I dont know why everyone is hung up on PA when they are going to try to count votes for a week after ED. Kick ass in MI and AZ (I think NC is in the bag) and this thing is over on election day while the Dems run around Pennsylvania trying to harvest votes.
