There is no real difference in McCain and a dim-0, but to put one in his place gives the dim—0 party 1 more in the total count of senators, putting them 1 step closer to control of the senate. With McCain holding his slot, that puts us 1 seat closer to the majority that we need so badly to take in the next election.
True...
I just hope McConnell wraps his mouth in duct tape...
