Coulter's fascination with the "most liberal Republican"

First it just "had to be Christie," now it just "has to be Romney," Ann Coulter says. I don't get it. I thought Coulter was more of a "go for the jugular" type. A regular contrarian. This is more like the puppy that lays on its back and exposes its belly while weeing on itself. She apparently really believes that American's want a Republican that is as close to Obama as we can get.
