Now that Ann Romney has a horse headed for the London Games, Olympic dressage -- of all things -- has become presidential campaign fodder for TV pundits.

Mitt Romney's wife Ann is a co-owner of a 15 year-old mare, Rafalca, who qualified for Olympic dressage, also known as horse ballet.

Expect to hear much more on TV about that, although it might not always make sense.

MSNBC talk show host Lawrence O'Donnell Monday knocked Mitt Romney for "rewriting the definition of an Olympic athlete." O'Donnell was referring to CBS' Bob Schieffer Sunday saying to Romney that "you have an Olympic athlete in the family" and Romney answering Ann is "the athlete, but in this case, it's not her personally."

Ann Romney took up dressage as a way to relieve her symptoms of multiple sclerosis. Harrumph, suggested O'Connell: "There are a lot of things you can do to try to deal with MS. But come on, dressage does not appear in any of the more traditional courses of treatment."

O'Donnell then said the horse is a business deduction for the Romney Limited Liability Corporation. Said O'Donnell: "Mitt Romney was afraid to identify a single tax deduction he would eliminate or reduce, but I think we can be sure that the Olympic athlete in the Romney family, the horse that masquerades as Ann's horse, but is never actually ridden by Ann, would continue to be a fake deductible business expense" if Romney were elected.

Can TV attack ads involving dressage be far behind?
