Always remember that senators can end a filibuster regardless of what the majority leader wants. At any point senators can go to the floor and get on with it.
McConnell might be known for filibuster, but that's key: his role was to be a scapegoat, to be known for the thing that the rest of the chamber set up.
A whole lot of powerful senators ducked accountability by blaming McConnell for their own choices, and we really need to call attention to that.
