Well the first problem is none of them are Biden's "subordinates". The second being Manchin and Sinema. Everyone knows if the filibuster isnt eliminated or at least carved out for specific bills like Voting rights we can't get anything done without reconciliation.
Manchin is already taking the wrong lessons from Tuesday night saying the results validate his concerns about spending and inflation. There should be 0 argument by any Democrat about the Voting rights act federally. Bi partisan support is out of the question since we are basically talking about saving minorities rights across the country from being trampled by nearly every GOP state administration. There is no way we should go into midterms without this passed with a filibuster carve out. Yet still you hear sanctimonious I will never vote away filibuster from these two clowns.
I mean we have all seen the GOP cheerleading these two clowns in their internal meeting leaks. McConnel gets to sit back cackling with glee. All the while Minority districts are getting carved up and representation in the house is going to be even more solidly GOP leaning
