Mike Huckabee's first ad is provoking all sorts of responses. Some say that it's not serious enough; others are just obsessed with the pop culture emination that is Chuck Norris.

The most salient fact to me is that the campaign purchased $60,000 worth of traffic -- not enough to really move votes on its own, but certainly enough to convince the media to play the ad for free, which, beginning on Fox News Sunday, it did.

The ad very gently addresses some of Huckabee's blind spots, including his record of support for in-state tuition for undocument immigrants. It also allows Iowans to put a face with the name -- ah, this is the guy they've been hearing about, and, huh, it turns out that he's a bit charming.
