If Biden or the Democratic party really cared about the country they'd pick a new candidate. It wouldn't take much to beat Trump and if Trump is such a threat to democracy then why run the worst presidential candidate of my lifetime? Why run the only candidate that Trump could possibly beat?
I think if they swapped that person would certainly lose, mostly because there just isnt another person that is both palatable to elites and popular (except maybe Michelle Obama?) to have people actually vote for them.
the weirdest thing to me about Biden recently is just how different he looks everytime I see him; some days it looks like fresh botox, then its like standard geriatric, then extremely greasy, then dry, then deflated bad facelift. Has he just ingested so much plastic that he has turned into clayface?
