The Chicago/Little Rock machine then played hardball with a threat to reveal his affair. Having done the wrong thing by having an affair, Petraeaus decided to do the right thing by resigning.
He will eventually testify truthfully, assuming he avoids Fort Marcy Park. However, before he testifies the mainstream media will treat him brutally and tell us he eats puppies for breakfast.
I can understand everything you say except this: the public announcement of the affair. Why did that have to come out, he knew it would hurt his reputation and devastate his wife. It seems like he was forced to hurt his wife and his reputation publicly, when one would expect a private request to step down and spare his wife (and rep). It was a humiliating scenario, why did it happen? There is more here than we are being told.
Petraeus was at odds from the beginning with O’bummer.
O’bummer got him where he could keep an eye on him - then sent a gal to compromise him - then sat on the ‘scandal’ until they needed it to shut him down or cover a situation like Benghazi.
It's the Chicago Way.
Unfortunately, Petraeus took the bait.
I wouldn't be surprised if he now has family safety being threatened to keep him for spilling the beans. (Remember Ollie to to put a security fence and other security measures from the threat against him.) Hope he doesn't ‘commit suicide.’
He's a good man caught in a web more evil than we have seen in our lifetimes. A good man and a long, honest and distinguised career delibrately destroyed.
