He is one of the few celebrities (besides Palin or Cheney) that could really generate added excitement. We don't have Jimmy Stewart or John Wayne.
Eastwood would also get even for doing that Chrysler ad that made him look like he was pulling for Obama.
I’m thinking Clint makes a ton of sense. As much as a lot of FRepers would like a conservative stalwart, it wouldn’t help sway undecided voters to Romney. So is the goal to fire up the base, or make Romney/Ryan more palitable to undecided voters? I think the latter. And everybody loves Clint.
