Tuning in a bit late to the GOP debate last night (I rated dinner with the family as more important) I missed this from Mitt Romney:
MR. FAHEY: … Governor Romney, I wanted to start by asking you a question on which every American has formed an opinion. We’ve lost 3,400 troops; civilian casualties are even higher, and the Iraqi government does not appear ready to provide for the security of its own country. Knowing everything you know right now, was it a mistake for us to invade Iraq?
MR. ROMNEY: Well, the question is kind of a non sequitur, if you will, and what I mean by that — or a null set.
And then again, a couple of minutes later:
MR. ROMNEY: Well, I answered the question by saying it’s a — it’s a non sequitur, it’s a null set kind of question…
A null set! I’d like to congratulate Mitt Romney on being the first to introduce a term from mathematical set theory into a presidential campaign… except that he plainly has no clue what “null set” actually means. If he DID have any clue, he’d know to say “THE null set,” not “A null set.”
