I know there was quite a large surge in Republican registrations in Pa. leading up to the '20 election. And I've seen a few articles of how it is continuing, and even more so, this year.
Talked to a lady (aunt of a friend of mine who was down visiting) a few weeks ago from the suburbs of Minneapolis. She is very pro-Trump and was telling me of how many people she knows, who are life long Dems, who she said will be voting Republican. Talked about how people are totally fed up with crime since Floyd, defund the police, etc. Hope she's right.
Article from April regarding Pa......
Republicans are registering formerly Democratic voters at four times the rate that Democrats are making the reverse conversion in the battleground state of Pennsylvania, a warning sign for Democrats as they try to keep control of the U.S. Congress.
