Biden may not be able to do anything permanent in terms of legislation, but there is tons of stuff he can do. He can undo all of Trump's EOs, and put his own in place. His people will actually know the proper procedure (unlike Trump) so the Supreme Court will not be able to overturn them.

He can also get competent cabinet members and agency heads, unlike Trump's political cronies and saboteurs. Doesn't need senate confirmation, if he just rotates them every two years.

Republicans will be able to do nothing at all that Democrats don't support, so if they want to actually pass anything, they need to get rid of the Hasturd Rule. So I think compromise is coming. Either that or they might as well just stay home.

If he does a good enough job, Covid goes away with the vaccines, and the economy comes back, then maybe the voters will decide they like his stuff and vote in more Democratic Senators in 2022.
