PA Statewide Referendum Primary Result vs. 2020 Result

[Skill and Chance]

Some businesses owners in Chester who were Biden voters voted yes

Also, you can see a significant number of culturally conservative COVID hawks out there in Scranton and the rurals (IMO a very underrated part of why Biden won and why, e.g. Appalachia didn't get any worse for him).

The biggest surprise to me is Centre, which is dominated by the largest college in the state being more pro-lockdown than pro-Biden?!

Philly
Biden +63, No +36, No +43

I think this is the key to these referendums succeeding. A 20 point swing in Philadelphia alone would turn PA into something like FL. If there is really this kind of change in political preferences then Dems are in deep trouble in PA, but I would write this one off as the result of low turnout and working class minorities who blame the state government's pandemic policies as having cost them their jobs/livelihood.

Extrapolating nationally, this is how Republicans win the presidential PV in the modern era.  I don't think we're there yet in explicitly partisan elections though.
