Yeah, I think there are at least 15 more Democratic senators that will gladly grab all the attention, money and career bosting that comes from being a Democratic senator obstructing progressive legislation.Yeah, we can rightfully be mad at Manchin and Sinema, but you're lying to yourself if you think removing them would fix this fucked up system. They're not the only Democrats tied closely to corporate interests, though I'm sure a lot of Dems are happy they're the one being so brazen/blamed for it.
As long as the carrot is this big and the stick against doing this is non-existent, this will not change, and I don't think you can get a big enough Democratic majority for that to not be an issue. Like they have won bigger majorities in the not so distant past.
