Clearly, they KNOW that all other candidates are pawns of the Establishment, and therefore enemies to Freedom and RP.
The lone exception may be Romney, but he's the frontrunner. However, I do not believe he is a true Insider. I've said it many times on here, and often get ridiculed, but I think Romney is just deceived, as are most Christians/Mormons.
I think there is a remote chance Romney could wake up. ALL THE OTHERS have already sold their soul to the devil. And the campaign knows this, so WHY issue this challenge?
It must be a PR stunt for the neo cons out there. The campaign is just using this as way to communicate a major point -- that RP is the only true constitutional conservative out there. And the best!
