This doesn't exactly
amount to an argument in favor of Santorum -- and as best I can tell, the post-debate polls seem to have moved slightly against him -- but it remains true, I believe, and thoroughly remarkable, all the same. In the words of Bill Kristol, writing at the Weekly Standard:
[W]hat's struck me about the commentary on the debate is how much of it is about Santorum. Commentators—and voters—seem to be either lukewarm or lukecool about Romney. But no one seems to be paying much attention to him anymore. His own campaign doesn't pay much attention to him, since they spend most of their time attacking Santorum. Is anyone—even his own campaign—really that interested in the Romney economic plan? Fairly or unfairly, it's now all about Santorum. He's gone from a 1 percent candidate two months ago to the center of gravity in the Republican race.
