Possibly, but who among the most likely replacements can pull the left together quickly enough to beat Trump? There’s only one Dem I can think of who could do that, and he’s moving out of the White House in January.

Whoever he backs.
Biden.
“Biden”
If Biden were to be the one, I think you’d quickly discover how little regard the left really has for him. He doesn’t have the right qualities to pull them together. Not a first banana.
