Mark Hamill - John McCain - The guy thinks he's Luke Skywalker, might as well play him.
Brian Dennehy - John Schwarz(McCain's campaign manager) - Doesn't look like him, but his Bobby Knight character fits perfectly after Schwarz's drunken interview where he lashes out at pro-lifers and pro-2aers.
Droopy Dawg - Joe Lieberman(His best friend) - Joey looks like Droopy. Nuff Said.
Bill Kristol - McCain's top butt kisser. - Plays the part so well anyway.
