.Doubt it. Doesn't have the central appeal of Biden. He has the environmental creds, but he would have also been painted as a pretentious twat to many undecideds voters, by the right.

its not like the clinton administration was liberal though and he ran with lieberman so i dont think he would have any problem whatsoever with moderate dems. the latter is more likely but is that any worse than how some of them feel about the narrative that biden is too old? theyd probably cancel each other out
