It’s a general election, party switching is irrelevant because every voter gets the same ballot. How much more data do you need to acknowledge that 2020 Biden support isn’t resulting in increased Democratic Party support?
I just mean switching the party they vote for not switching registration.
Telling me that previously, 60% of a demographic group voted for a candidate in one party and then in a different election 62% of that same demographic group voted for a different candidate in a different party doesn’t tell me much without more data. Maybe the exact same people voted for the exact same party but a big chunk decided to just stay home, so the percentages look wildly different but the number of people that voted for the gop is the same. There is no evidence of a huge swing in support for the GOP without more information.
Having said that. I agree with you that Biden’s support was slim and largely based on anti-trumpism. That is not a winning strategy when trump is not on the ballot.
