Biden refused to run a campaign and administration that provided any meaningful progressive vision and then he dropped out only after it was too late.

Of course he does.

edit -to be fair to Biden his administration did get a lot of wins, such as some great environmental policies… but I am talking about a broad vision and rhetoric. An actual alternative to Republican visions of catastrophe that challenge the flawed assumptions at the heart of conservatism. Exhibit A) is how Biden and other powerful establishment democrats never really pushed back on Republican narratives about immigration which opened the door further for Trump to dial things up to 11 in his cruelty towards immigrants in his second term
