If I wrote an elementary logic textbook, I would use this from last night’s debate:

Mr. Huckabee, for his part, responded with trademark humor. “The Air Force has a saying that says if you’re not catching flak, you’re not over the target,” he said. “I’m catching the flak; I must be over the target.”

Similarly, if you’re not an American citizen, you’re not President of the United States. I am an American citizen, so I must be President of the United States.

Ahh, nerdiness, I bask in your glow. I hasten to add that the above-cited Huckabee statement bugged me when I first read it, but I didn’t really dwell on it. I guess that’s one more thing that separates me from being a brilliant Harvard academic.
