Doesn’t matter. The point is that Hillary cannot take them for granted.
Trump is going to campaign everywhere. He is going to hammer the issues that Americans care about, borders, immigration, trade, jobs. Those are the winners. Trump will have folks voting for him that want someone on their side not the DC political class
Whatever else may be true about Trump, he LOVES America. Hillary does not she loves Hillary
Depends on if the Unions in Pittsburg can generate enough votes for Dems. If Allegheny county PA votes republican, PA shifts.
