Battle o’ the campaign narratives this morning on NBC and CBS. Santorum will hammer the point that Gingrich is hopeless if he can’t win in Alabama and Mississippi on Tuesday and that conservatives’ last chance to stop Romney is to unite behind the Sweater Vest. Newt will counter that that’s not true because, well, er, it just isn’t. So there. If you’re bored with the primaries, try “This Week” for the cameo by former McCain staffer/Palin critic Nicolle Wallace, who evidently emerges as the heroine of HBO’s “Game Change” movie. Go figure.
