A fun number in this week's big Gallup poll: Karl Rove's favorable rating has edged all the way up to 21%. That's a two point gain from last November, when his rating was mired at an abysmal 19%. Strikingly, less than half of Republicans -- 42% -- see Rove favorably (though that number does dwarf the 22% who see him negatively). Maybe his MC Rove performance will help matters, and he'll boost himself all the way up to 23% by next fall.
