It wouldn't surprise me that in fact neither Biden nor Obama were "in the loop" as far as Libya was concerned. Given Hillary's remark after the overthrow of Khadaffi, "we came, we saw, he died," she would seem to be the one heading the Libya operation. When you couple that with the documented fact that Obama can't seem to make a decision, bypassing him on day-to-day operations wouldn’t come as a surprise.
If that is the case, it is doubly damning for both Obama and Clinton. On one hand, you have a secretary of state that is conducting clandestine foreign policy and on the other, you have a president that is so disengaged and clueless as to allow it. Methinks both will die politically by the sword they wield, AKA, the lie.
