Biden barely won last time. And the only reason was because he clearly was the lesser evil. Now Biden is just as evil as Trump he will no longer get all those votes.
Either he gets replaced as a candidate as quickly as possible, or the Democrats will lose this one. Because there are too many non-cultist democrat voters which have "committing genocide" as a red line that they will not cross.
Whereas Trump cultists will 100% vote for him no matter what happens, the Democrats have to actually play their theatre role of "being the good guys" and Genocide Joe went full mask off Nazi this time.
