Now that the dust has settled a little from last week's Iowa caucuses, we can see that while they didn't give Mitt Romney everything he wanted, they have certainly reshaped the Republican race in a way that's highly favorable to him. Three things in particular must make Romney very pleased with the Iowa result.

First, he won -- incredibly narrowly it's true, but a win is a win, and for most of the last six months any sort of Iowa win seemed highly improbable for Romney. Among other benefits, winning should sink the campaign of Jon Huntsman, Romney's only moderate rival, whose strategy depended on Romney being badly hurt in Iowa. (Huntsman didn't campaign in Iowa, but even so the fact that he received less than 1% must be pretty galling.)
