Posturing. The old fool knows he’s got a tough re-election fight in Arizona coming up so he wants to show he can get some support in the primaries to parlay that into a cabinet position in the next GOP administration. Most likely he’s seeking to be Secretary of Defense so he can follow in the footsteps of his buddy Chucky Hegel.
I hope Sarah Palin primaries him. Popcorn sales would go through the roof.
