The priority right now is get Trump out of the paint. I support leftists forming 3rd party structures, the labor movement getting teeth again, and people on the streets everyday demanding Biden and hopefully a Dem House and Senate do something to improve material conditions of people. I think we will see mass civic actions in 2021 with the economic crisis continuing and the COVID-19 pandemic hopefully coming to an end.
If Biden doesn't govern effectively, if the Senate filibuster is not abolished, he will not be able to do any of his agenda items. And if he doesn't govern, things will get really ugly for him very quickly.
Right now you need 60 VOTES to pass legislation in the US Senate.
If the Dems win the majority by a couple of seats, Mitch McConnell will block ANY agenda item from Biden. So his healthcare plan, his climate plan, his immigration plan, his stimulus plan, and voting rights/democracy plans won't get anywhere.
The Dems will have to fukking wield their power and nuke the filibuster so they can pass all of their agenda with 51 votes. In hindsight, Obama should have did this in 2009 and 2010 when the Dems had 59 Senators and the US House.
The current US House controlled by the Dems has passed MANY bills that McConnell has let die on his desk.
Getting Trump out is priority 1A but winning the Senate is priority 1B and getting rid of the racist filibuster is priority 1C.
Otherwise, NOTHING beyond 2 budget reconciliation bills reversing the Trump tax cuts stuffed with some priorities will be able to pass in 2021 and 2022. And if Biden ain't governing, he will become unpopular fast. Very fast.
So the best thing about Kamala Harris is she wants to get rid of the filibuster. Let's hope she takes interest in policy. I'd like to see her go after power like the tech monopolies, the banks. But I know, it is unlikely.
