Yes, both states are gone going forward. The Republican party is now the party of the white working class, and this won't change regardless of who manages to win today.
Eh, I mostly agree. But I really think people undersell how fluid some parts of the electorate can be. I could be wrong here, but I think with some Hispanics there is a huge response to incumbency. They seem to like the familiar. That’s not to excuse Democrats (and this is not just a Biden problem, the blame does not go solely to him) poor messaging/out reach to that community. But the re-election of Clinton, Bush, Obama, and, now, Trump saw favorable swings toward the incumbent. I think the fact remains that this is a naturally Democratic constituency, but Democrats have to work for it (see how they responded after Bush’s strong performance with that group in ‘04).
White working class voters are a much larger problem. I don’t think many of them are coming back. Apologies to Hillary because it didn’t seem to be her. They were looking for a reason to bolt for a while and they did en masse in 2016. What’s developed in 2020 is that rather than being “missing” white voters, these voters are no longer missing. They’re voting. Truth be told all the years that we were told how Democrats benefit from high turn out doesn’t look to be true at all.
