One thing, I have noticed over the years at my place of employment, is how people who identify as republicans no longer discuss policy issues. I am surrounded by white men mostly without college degrees, who are mostly in their 30's to 60's and who make relative to other American workers, high incomes. I remember them debating the Iraq war and the war on terror, or talking about "gay marriage", or guns, or gold, or all manner of stuff I didn't agree with, but at least they were discussing actual policy issues.
Now they discuss how Kaepernick kneeling was disrespecting the flag when that was happening a few years ago, or how Hilary Clinton is a serial killer, how the media hates trump, how socialism is bad, covid is a hoax, an experiment in government control, how trump is fighting a secret war against Hollywood and democratic party pedophiles or voter fraud is a huge hidden problem.
It seems that all of the stuff they used to pretend to care about, are irrelevant, they don't discuss actual problems facing Americans, they want to discuss "culture war" fictional nonsense or strange conspiracies.
Whether trump wins or loses, what policies do his supporters actually want? I have no idea.
