Yep, that must be the reason

David Petraeus just resigned as head of the CIA because he had an extramarital affair after 37 years of marriage.

I honestly cannot recall anybody else who resigned from public office this way. There have been people who have been caught in affairs, and have stopped running for public office as a result. But to -- as best I can tell -- volunteer that he had an affair, and then just quit?

Especially a guy who's in charge of the CIA, who runs all the top secret cloak and dagger black ops that this country engages in. He's really that straight-laced?

I mean, I've seen the James Bond movies, and, well.....how disappointing.

Looks to me as if Petraeus was just looking for an excuse to get out, and this was the best he could come up with.

He should have tried something a little more credible, like the classic "wanted to spend more time with his family" line.

Yep, an affair. I'm sure this had nothing to do with how the administration refused aid to those four men who were killed in Benghazi. And I'm sure the timing -- three days after the election -- was entirely a coincidence.
