I think people forget that PA had no in-person early voting and also required an excuse for a VBM ballot before they changed things in 2019. Hillary did a good job during her campaign in getting voters out in early voting states like Nevada and Florida(she actually had a huge lead in Florida prior to Election Day that had most predicting she would take the state but Election Day voting there was an absolute Trump tsunami). If Pennsylvania had offered no excuse mail voting, I think it's likely we would have seen Hillary perform better there than she did but still lose the state since things were overall going well pre the Comey letter. Pennsylvania has somewhat surprisingly to me been bluer than Wisconsin pretty consistently after Trump's 2016 win. Of course, in 2018 there wasn't no excuse needed mail voting but I think this is an interesting question. Thoughts?
Clinton did in fact do better in PA than WI in 2016.
