You’re still making the mistake of treating dems like some single monolith. It’s a coalition of just about everything that isn’t MAGA at this point, covering all sorts of ideals, yours being just one small part. The answer is still “get a majority of reps that aren’t asswipes” and then we’ll get legislation we want.
As to DC statehood, it would have gone through if not for Manchin because the Senate “majority” at the time hinged on his support. We need to win these seats with bigger majorities, period, and then they’ll pass better bills. The overwhelming majorty of Dems support DC statehood, saying “they won’t do it” is not a great take when they literally didn’t have the votes.
