Going on a show doesn’t mean one adheres to the beliefs of the host. Rand Paul is not a truther and it is disengenuous to suggest so. If anything he has disappointed some of his fathers faithful because he refuses to take the isolationist stance of his father.
But Rand Paul did announce his candidacy on the Rachel Maddow show. A strange forum for someone seeking the Republican nomination.
Does proudly excepting the endorsement of said host do so?
