Trump isn’t in any way an unknown and he’s made his ‘policy’ opinions extremely clear, to the extent anything he says is clear. He also had 4 years of a presidency with a pretty shitty record on just about everything except getting abortion banned, packing courts with religious ideologues, and tax cuts for rich people. This next election is just as much ‘oh please anyone but fucking trump’ as the last one, and Biden did have tons of people voting against Trump as much as voting for Biden. But sure, Americans love this stupid “Let’s give the other party a chance” thing and have short memories and poor sources of information.

Should Biden be running only on “I’m not Trump”? No, of course not. It is still a factor though and he might actually have a harder time against a different opponent. I would love for someone younger and sharper like Gavin Newsom to step up, but both national parties are in shambles right now - the RNC with their near-total ownership by Trump, and the Democrats doing the same stupid shit they did when Bernie was running and not giving other candidates a fair chance.
