McCain will behave if/or until we have a GOP POTUS. Aw geez, he is a maverick. *snort*
If we get a GOP POTUS, McCain will crap all over who that is.
He shouldn't care at all in a political sense any more.
He, like many others in the senate, should have just faded away years ago and enjoyed their golden years for crying out loud.
They just can't "be normal" and stop working at a decent retirement age like the rest of us do.
I bet he would make a GREAT part time door greeter at Walmart!
