If you want a celebrity to appeal to younger people use The Rock,Arnold, Chuck Norris, Steve Austin, or some conservative celebrity who represent values we can embrace. What is not conservative about kicking serious @ss!
The Rock was at the convention in '00. But, wrestling has taken a major downturn in the past four years. Doesn't get anywhere near the ratings it used to. That kind of knocks out The Rock and Steve Austin.
Chuck Norris is probably a joke to most people under 25. After all, you have to admit, Walker: Texas Ranger was kind of a cheesy show.
Arnold is there, but he doesn't have the same "street cred" he used to, now that he's a politician too.
Call me crazy, but I don't have a problem with Britney being there. I think she could add some spunk to the convention.
