Heilbrunn mentions that Gaffney has been waging a long-running smear campaign against Grover Norquist, but the more significant lie that Gaffney has been spreading for years is that U.S. foreign policy is being directed by the Muslim Brotherhood. That is just one of his many absurd claims over the years. This is the sort of unhinged, obvious nonsense that is usually not even worth addressing, but since one of the top two Republican candidates for president is listening to someone like this it worth calling attention to it. Cruz has proven once again that he has terrible foreign policy judgment, and he disqualifies himself by indulging the worst sort of conspiracy theorizing and alarmism.
