McCain will give it the thumbs down for the kill.
McCain will fight it...but, and I'm not trying to be mean here, if the Republicans keep sending it back...will Mccain still be around to fight it next year? Doesn't he have aggressive brain cancer? (NOT wishing him ill...just being realistic.)
Probably but his buddy Flake is in real trouble.
McCain giving the thumbs down would probably be the end of Flake in AZ politics.
and the end of McCain eventually.
