I thought Clint went on record that the Super Bowl ad wasn't a political pitch for either side, it was intended as a morale booster, just a pure non-partisan pro-American thing.
It was meant to be a message … just about job growth and the spirit of America. I think all politicians will agree with it.
Whatever, that was months ago, he is entitled to take a side now if he wishes to.
Anyway, the TBA mystery speaker has certainly worked as a publicity stunt, generating interest in what would otherwise be a by the numbers convention finale. Everyone from Clint to Ronald Reagan's ghost has been speculated as the TBA. WOO!
Well, we'll see. I expect it to be, actually, a passing of the baton, either Dubya himself or former VP Cheney. A political big gun moment.
