So some analysis
At this point, it should be obvious there will be a floor vote no matter what. The odd thing is though, while usually if mcconnel were to bring something to the floor it should be assumed to be locked up, we can't be 100% confident this time around.
I think the calculation they should probably see in front of them is that they will look way too weak acquiescing to these smear tactics, and the voters will eat them alive. So at this point it's better for republicans to bring it to the floor and have it fail than to pull it entirely. Long way of me saying it's never going to be over until it's over.
Then we have the flake factor and how badly he wants to fuck us or be a little bitch. Given his term is going to be up and he's not going to be a senator anymore, he's ripe for bribes or cushy promotions likely being offered by democrats when he gets out of congress. So I worry about him a bit. We can afford to lose one.
