For the four Republican senators who claim they are interested in opening the government again, I would be more impressed if one of them lead a leadership fight to remove McConnell.

I wouldn’t expect the GOP to support a Democrat in that position, but Collins, Murkowski, Isakson, and Capito (the ones who are calling for the government to be reopened) could put one of themselves forward.

I suspect if this goes on long enough they might, though you might wind up with a split between GOP senators who support McConnell or one of the others.
