This red herring was of Petraeus own making. What is not known is if he was 'blackmailed' because of it to do Obama's bidding. Conveniently now Petraeus's red herring allows him to sneak out of testifying about what really did happen in Benghazi. Not every one reads these avalanche of reports of Petraeus's red herring to find out the salacious details of some idiot's sex life.
Whatever.
