 Let me ask you a tougher, more personal question. Are you sure you're being honest with yourself when you say you have the mental and physical capacity to serve another four years? Yes, I am, because, George, the last thing I want to do is not be able to meet that. I think, as some of the senior economists and senior foreign policy specialists say, if I stopped now, I'd go down in history as a pretty successful president. No one thought I could get done what we got done.
