The filibuster rules are just that...silly Senate rules. It’s not in the Constitution.
Mitch should dump it or resign and get the hell out of the way.
I’m sure McConnell is not the one standing in the way of abolishing the filibuster. There are a lot of Republicans who would oppose that. It only takes a majority to abolish the filibuster and they obviously don’t have it or they would have done so already.
