My prediction:
Virtually all of the 80 million people who live in Philadelphia will end up voting for Hillary.
Trump’s team should (armchair QB that I am)scrutinize all of the Cleveland and Philadelphia precincts that went 100% for Obama in 2012. I don’t know if poll observers will do it. (just like Hillary had Secret Service agents “guarding” her server).
I believe Philadelphia enjoyed a 116% turnout for Obama the last time.
