I suspect that Biden thinks he is still in the senate - he isn't. Its strange, I think he knows it but habits die hard. Eventually (hopefully) he will actually start behaving like the president and not the senator.
Between that and the unfortunate behavior of the Dems they either gotta start behaving that they are all in the same boat, start, at least, working on a message, and getting over their personal wishes.
If they don't do that they are going to get a really serious education next year. Its really a shame, they should have passed the infrastructure thing and went to work putting themselves together to actually win an election.
