Krauthammer has never been a fan of Sarah. I've gotten the whiff of sexism in his previous comments but beyond that, he's "ruling class" all the way. Tonight's comments from him bear that out, as well as the analysis from others on this thread.
BTW, his calling Sarah's endorsement "capricious" was simply ignorant and foolish. Not like Kraut. All this silly "grassroots" stuff must be getting to him...LOL.
