If the Democrats do push Biden out, I predict there will be no consensus on a replacement candidate, leading to infighting and, ultimately, a realization that the Democrats have a stable full of flawed candidates that cannot gather national support, particularly in a short time window.
I don't know. The case for Biden is increasingly becoming no more than "He's not the felon, autocrat, insurrectionist, rapist," etc. Any replacement candidate would have that going for them and possibly more.
