im sure part of it is correct the record 2.0 (like Russian bots but real) and some of it was bound to happen organically when people had been preaching vote blue no matter who for the past 2 years. Biden wins and you see them doubling down in favor of him, they've gotta convince themselves their liberal world view still makes sense, biden isn't a bad guy, he'll fix climate change, etc etc. That one democrat was talking about how badly Trump fucked up the coup, now a perfect storm for manufacturing consent on the only other super power that contests the US. There's so many reasons.
