I'm in PA and I had two signals that Trump was going to take PA. Not 100% confident, I admit, but a gut feel.
One was when I went to the Trump rally in Hershey, PA in late October (at the urging of my 16 year old son, who really wanted to go). Driving out there from eastern PA, all I saw in the area were Trump signs in yards, everywhere - and I mean everywhere. And not a Clinton sign in sight. And the place held 12,000 and it was full, and there were still thousands outside on a cold night who didn't get in.
But the real sign to me was when I heard Clinton was holding an election eve rally in Philly. I live in the Philly suburbs and Philly is about as close as you can get to a Democrat mortal lock. I thought it was very odd that she would have to go to Philly on election eve - why not a "close" state, or area where she needed to pick up votes. When I heard she was coming to Philly, I remarked to a coworker "she doesn't have PA locked up", and she didn't have PA, she didn't have the other battleground states.
I think it’s divine justice that the skewed polis ended deluding the Clintons into screwing up her campaign strategy. Neglecting the Blue wall etc. To an extent l fell for it too but when l saw Trump spent some of his last precious time in Mi I thought “hmm.. This is odd, Mich must be in play, that’s not supposed to be”. I have no doubt the Rats cheated, a lot, but with the polls saying what they did it caused them to cheat less then they needed to.
