I recommend reading this article. A win does not hinge completely on PA, but since it has 20 EV, it is the one state that gets him over guaranteed, if all traditional red states still vote for President Trump.

Good article. I actually believe that Trump will take all the states he took last time and add Minnesota. Pennsylvania is thus made immaterial.
