Nope; they just implied it. Well, the inference that fueled the implication seems to be nothing more than balderdash. Mike Huckabee's campaign put together a great ad with Chuck Norris. Pretty shrewd as well, as the candidate who isn't taken that seriously is being paired with a celebrity who is also aware of his own less than highly esteemed public persona, and can laugh (stiffly) all the way to the bank.
On top of that, Mike Huckabee can now count on two types of voters - his primary base of Ted Nugent type survivalist conspiracy theory nutjobs, and the type of young, irony obsessed idiots that put Jesse Ventura in the govenor's mansion.
if the democrats want to get a tasty piece of the irony pie, I think that Senator Obama could be well served by doing a similar ad with his caucasian counterpart, Leonard Nimoy. Take it one step further, Senator Clinton should rope in Will Ferrel doing his Janet Reno bit - or better yet? Darrell Hammond as Bill Clinton.
