I can recall certain Republicans saying that celebrities should not stick their nose into politics. Hmm... What's Arnold again, oh yeah, he's an actor! So was Reagan (Although Reagan really belonged in politics, he was not very good at acting.). I don't think I'd ever vote for Arnold. I only liked Predator and Running Man. LOL.
The difference being that Arnold has acctually put his money where his mouth is. I respect Bono and a handful of other Liberal celebrity activists as well, because they aren't like these Liberals who just go to cocktail parties, here what everyone else is saying and then head to the next Bash Bush rally.
