Bill Kristol takes Mitt Romney to task. Kristol, one of the very first analysts to see real potential in Rick Santorum, has good political sense. Four years ago, he was probably the first serious writer to start suggesting that Sarah Palin would energize conservatives if John McCain picked her as veep (months before the selection was made). Whatever one thinks of Palin, Kristol’s analysis about her effect on the conservative grassroots was right on target. Other examples abound. As a pure political analyst, Kristol is usually ahead of the curve. And I think he’s on to something here when he says that Romney’s attacks on Santorum so far are falling flat.
