No, this is what makes many on FR think he's a nut:
Associating with Code Pink - Associating with 9/11 truth - endorsing and going out on the stump to aggressively campaign for Adam Kokesh, a well-known Code Pink Activist, 9/11 truther who went overseas to a military base and asked troops to abandon their posts, was responsible for the campus slander campaign against students putting up fake racist flyers and attributing them to a conservative student organization, etc. Saying that Israel set up Hamas. Making absurd statements that the U.S. could have simply 'bought' all the slaves and prevented the Civil War. Saying that a Yale Fraternity is controlled by the Trilateral Commission. Saying that "If I were Iranian I'd want the bomb" - we aren't interested in what he would want if he were Iranian we are interested in what he would want as an American. Repeated appearances on the Alex Jones show. Endorsing Cynthia McKinney - Etc, etc, etc, etc...one could probably continue the length of a book with example after example of this silliness.
That's the sort of thing some of us have a problem with - not that he's an alleged "constitutionalist" as has been discussed here numerous times.
You can judge a man by the company he keeps...
