Petraeus resigns as CIA director. We’re watching Fox News as we type. Per Fox, in his resignation letter, Petraeus admits to having an extramarital affair. We are now speculating why this is coming out at this particular time? Is Petraeus setting the stage to throw Obama under the bus over Benghazigate? Was he being blackmailed? Was he afraid this would come out at the hearings on Benghazi?
