What Happened to Petraeus for President?

I’ve never found the idea of General David Petraeus as the 2012 GOP presidential nominee to be particularly plausible, but today’s performance would seem to really be the nail in the coffin. Nobody knows what his views are on domestic policy, but it seems impossible at this point to imagine a Republican nominee who believes in the rule of law and humane treatment of detainees. And that, in turn, is obviously a sad state of affairs.
