  In interviewer asked Cain if he agreed with Obama's policy in Libya.  Cain moseyed around but could not answer.  He later said that he didn't sleep enough or that it was  nit picky but it's common sense that he's not telling the truth.  He just didn't know this common knowledge foreign policy question.  It's just incompetent.  See the interview at Click here.
