A lot of Manospherians are commenting on the relational aspects of this whole debacle. And they are far more correct regarding the motivations of Petraeus and Broadwell.
However, the entire narrative is being used to divert the country away from the treasonous crimes this administration committed by denying available aid to American citizens and ambassadors abroad and watching them die. The Last Refuge does a brilliant job of collating and parsing the information and getting really into the truth of the matter.
This entire bit of political theater is designed and perpetrated to draw all attention away from those facts. They know for a fact that it will hold the attention of stupid Americans while they scrub their treason and blood off the walls.
