Pennsylvania isn't going to Trump. I'm more confident of Biden winning PA than MI or WI. Hillary hit rock bottom for Democrats, getting 50% in Lackawanna? Combined with her lukewarm performance in the Philadelphia suburbs, all Biden has to do is a modest over performance.
Hillary had the smallest drop yet Trump had the biggest gains out of any of the Rust Belt states he won.
All Biden needs to do to win is over perform Hillary in the suburbs and Scranton and Pittsburgh. That shouldn’t be a problem.
