Republican presidential candidate Mike Huckabee admitted to CBS host John Dickerson on Sunday that he did not know of any modern debate that had been won by invoking Nazis. In an interview with Breitbart News late last month, Huckabee had suggested that President Barack Obama's administration would trigger a second Holocaust by negotiating a nuclear deal with Iran. "It is so naive that he would trust the Iranians,” Huckabee complained.
