My guess and it is just a guess, is that they have been holding this over his head for a while and that is the reason that he accepted the CIA post, when he really wanted to resign.
I think as long as he used condoms provided by the government It all ok in our new world under democrats. but if he didn’t and his girlfriend became pregnant, that would be ok as well because Obama would help them go to Planned Parenthood and schedule an abortion and then even if it didn’t work and the child survived the abortion, Obama believes that the Doctor would be able to murder the child.
And if the doctor saw Patreus and they liked each other they could get married and smoke some together. So why would he resign? They could listen to some Jay-Z.
