Mohammed Morsi's #1 campaign pledge to Egypt was to get the Blind Sheik freed from U.S. prison. The plot to get Stevens kidnapped was on because there was a fear that Romney would get elected and any release of the Sheik would be off the table... This is why Hillary stripped Stevens of his security and denied him increased security. Hillary and her BFF Morsi conspired to get Ambassador Stevens kidnapped, to later be swapped for in exchange for release of the Blind Sheik.
Hillary conspired to get Stevens kidnapped and this is why the refusal to send in assistance after the attack and the resultant cover-up afterwards.
