In my opinion, the overthrow of Morsi in Egypt spoiled Obozo’s overthrow of Assad in Syria & that disillusioned his Saudi masters.
He is clearly fearful of same thing that happened in Egypt will happen in the US. Peacefully or not.
He thinks he can rig the elections again and get away with it. BUT if his crimes are fully exposed, this could lead to his rightful removal.
Exposure of Benghazi & related events must happen. Wherever it leads.
