I don't think any of us ever said he was smart enough to not engage in an extra-marital affair (or rape for that matter). He always thought he'd get away with such. He's a sexual predator among other things and his sort always thinks they can get away with whatever they do in a sexual and moral context. Ultimately that's why he surrounds himself with attorneys. I doubt that translates to his having the ability to (or believe he can get away with) having American operatives pull off mass killings of innocent Americans. His overriding concern, as we all know is himself. If he or anyone connected with him were associated with the actual implementation of the OKC bombing, he'd be history, as would the democratic party. No matter how careful you are, you run a HUUUGE risk trying to pull off something like that. And you have to know that it's going down and when. I'd love for it to be so. The guy would be buried as should have been the case long ago.
The cover up of a Muslim connection to the attack is possible, but not overt acts by clinton to facilitate it. It's a fanciful dream and nothing more.
