50% never liked him in the first place.
He has a passionate but still fairly limited base. Biden isnāt as personally unpopular as Hillary, any swing voters who thought theyād go fro Trump just to see what happened wonāt brother again, and no president has won office in the midst of the kind of crisis the US is currently in. I canāt rule out a trump win because we live in the worst possible timeline, but the numbers for it really donāt add up.
Given than Bidenās Democrats are basically Dubyaās Republicans though, thereāll be a whole different set of issues to deal with.
