I wonder what a county map would look like with a Dem winning PA by 18 points. I worry that that Dems would just be getting North Korean like levels of support in Philly and Pittsburgh, and getting slaughtered less badly in the center and southwest. Seeing Hillary losing Erie and even almost losing Scranton was scary to see.
Casey actually won by 18 points in 2006, so it would be pretty cool to see a 2006-2018 swing map if he had a similar margin this time. It might even be sig worthy.

I don't think he actually wins by 18 though. Barletta's numbers will probably improve a bit as we get closer to election day and his name recognition goes up. But the prospect of him even getting it within single digits is starting to look like a stretch.
