Gen Clark? HA! Listen to the guy speak (being in the Air Force, I've been forced to). Read the first couple of chapters in his latest book (that was just out of curiosity). He's a whiner. He's really good at looking back and, with near perfect hind sight, pointing out people's mistakes. He's also fairly good at pointing out successes. However, when it comes to solutions and policy changes, I have yet to hear an original thought from him. I don't understand why he is so popular in the Army. If he stays in this race, that will come out.
In any case, my worry is this: The world already thinks we've gone ultra militant. What will they think if we toss aside our current president in favor of a former general? Granted, the worst of these thoughts will come from the lower ends of the education ladder...
