caucus. someone like mark kelly of arizona has not said how he would vote. others like jeanne shaheen and maggie hassan of new hampshire have not said how they would vote. if you unlock manchin, if you unlock sinema, other democrats won't stand in the way. if you're not willing to be out front and vocal in favor of your strong support for a senate procedural tradition, then you probably are not going to stand in the way if the leader of the party decides to call that vote and hit the nuclear button. this is how it's always been in the past, before democrats weakened the filibuster for most nominations in 2013, many members were skeptical. they came around before republicans abolished it for the supreme court in 2017. almost to a person, they were against weakening the filibuster and they came around. the idea is if you convince the two most prominent opponents of the filibuster, that would be the end game. it's not clear if the january 6th filibuster didn't change their minds, what will.
