They lost didn’t they? That sounds like a win.
Yes, I'm aware that you think this way. Ukrainians, Gazans, people in the West Bank, "illegal" immigrants, legal immigrants, scientists, working people, journalists, and lots and lots of other people have already been sacrificed so that you could get your "win." Good stuff! Have you talked to them about how proud you are of the desired outcome? We're only a couple months in. It's going to get much, much worse for them.
If you want to make the US system better, including the Democrats, that sounds absolutely fucking fantastic. Simply not voting for them until they get better on their own, usually pushes them to the right, not the left. That's pretty much what happened from 1969 to 1993, and what turned the party of JFK, LBJ, and Jimmy Carter into the party of Bill Clinton, and ushered in our current shattered state. If you want to keep going that direction, you are not on the left.
