I’m withholding final judgement until I find out if the Republican committee members asked the really tough questions. If they get hung up over who said what after the attack, they will never uncover the truth about what happened during the attack and why Americans were left in harms way when military support could have been provided. There are so many grand conspiracy theories about gun running and Obama deliberately letting the Ambassador get captured to trade him for the Blind Sheik, but the more plausible scenario is that Obama let political considerations (i.e. appeasing muslim sensitivities) interfere with his duty to the Americans in danger, and that it was Obama who ordered the CIA and military not to send in any direct military assistance to the people at the Annex. Obama looked into the eyes of terror and he blinked. And Americans died because of his cowardice.
One problem with your analysis: the adminstration had this video excuse ready to go somehow. What a ridiculous, laughable misdirection. That this is what they are reduced to using, tells me that thy are covering something dramatic and utterly indefensible.
