I think that a lot of people have an overblown concept of what Democrats can get past Republican obstructionism, and nebulous concepts like "holding senators accountable" are pretty useless.

The way Democrats get policy past the goal is to inspire the electorate to fight with them. That is where establishment Democrats fall flat. Far from being ready to use an energized electorate, they are actually afraid of one. Their campaigns are literally designed to soothe the American spirit to sleep. That worked when the middle class felt secure, but not anymore. We don't just want competent administrators who can keep things running, we want reformers and visionaries who aren't afraid to shake things up. That scares the shit out of the establishment.

Trump was a molotov cocktail aimed at DC, and Biden was a response that said "we don't hear you, go back to sleep."
