This final note today from the campaign trail. We been talking a bit about super PACs this week, groups that can spend basically unlimited amounts to support the candidates of their choice.

Anyway, Newt Gingrich is telling his super PAC to back off. It released that anti-Romney video yesterday, taking him to task for his time at Bain Capital. This morning, “King of Bain” — as the video’s known — got a four-Pinocchio truthfulness rating from the Washington Post.
