It’s vitally important that Democrats now ask one question and one question only: Does Biden have the best chance of beating Trump, or is there someone else readily available who has a better chance?
Bernie would still win. Just has to publicly recognize his old age while also showing that he's not senile like the other 2, agree to one term, pick a good young progressive VP, and start hammering away at progressive messaging. Probably outright tell the center Dems it's THEIR turn to hold their noses... Unless they want Trump to win.
