Ron Paul has disassociated himself numerous times from truthers....If he did it a thousand more times, you just find some excuse to smear him.
As you'll note from the article, Willis Carto is a prominent neo-nazi/Holocaust denier.
I suppose he can't do much about loons like that supporting him, but Ron Paul is still advertised as a columnist in the American Free Press media guide. For their print publication. He can do something about that, and should.
Same goes for the Council of Conservative Citizens, who also claim him as a columnist in their print publication, The Citizen Informer. He should do something about that too.
IMO, while he's at it, he should stay off radio shows like Political Cesspool, unless he's there to condemn the racist fare they often put on.
Any yes, I understand his supporters disagree. But they can't feign ignorance when he gets support from places like duke.com and stormfront, he markets to them after all.
