John, it’s true that Clinton is famous for his temper, but he very rarely let it show in public. I think he let it go on Fox to bully anyone who would question him about his (weak) record on terrorism and to get some licks in against Fox News. Democrats are united by few things these days — but apopletic rage against Fox News is a universal. Further, Clinton has the slightly crazy capacity to convince himself of his own lies and then to become ferociously indignant at anyone who questions them. Above all, bullying works. Let’s see how long it takes for some other interviewer to pose similar questions to Bill Clinton.
