PA is already well in play, without Shapiro. No reason why a good VP pick from somewhere else doesn't pick up some more PA voters, plus not turn away some people who have been re-enthused about Harris both there and elsewhere.I think it will be Shapiro. they seem to get along well, and will make a formidable ticket. they'll also bring PA into serious play, which will likely decide the election. we'll know in a couple of hours, but he's my tip.
But, if I bet on these things, Shapiro is the bigger name, from the bigger state, despite problems they'll then face elsewhere.
