If GW really wanted to tear up the race for next year...when Cheney says he has to retire...then bring in Jeb Bush. That would reset the entire election scheme of both parties. I don't think Jeb would refuse the matter. And correct if I am wrong...but we have never had two brothers running prez and vice-perz at the same time? I can just see the look on Hillary and McCain's faces...when this would be announced.
But seriously...in a real world...I'm guessing he'd invite Fred Thompson over. Fred knows the senate and has alot of face time with the media. Fred also is a southerner who connects to people.
