This "Dems clearly don't want to do anything!" narrative is still mad fucking dumb. Yes, there are procedural challenges that mean even with the House, the Senate (sorta) and the White House, there's some stuff we simply can't do. That's the way the system is built. Wanna change it, yeah, you need more Democrats. For God's sake, I beg you, read a civics book. I get that the average voter doesn't get the details but if you're posting in what is nominally the politics enthusiast thread you should really be able to figure out why things happen the way they happen and not just go for the immediately cathartic answer.
Short of kidnapping their families or blackmailing them, nothing is going to get Manchin and Sinema to vote the way we want them to vote on the filibuster. Shit sucks. Gotta figure out another way, that way almost certainly *not* including the only politically potent group in the country actually opposed to the Republican agenda!
Look at what's happening in Texas! Look at the effects of the climate crisis! If you wanna have an intra party slap fight after we've gotten shit done, be my guest but until then it's gotta be all hands on fucking deck.
