Check out the final frame of this ad in Pennsylvania -- the speech clip they use of Obama's -- and you tell me:
It's not hard to guess what they're responding to, but in doing, they're going into the final day of Pennsylvania more off-message than they generally do. My sense is that Obama's been better off mocking these assault on his patriotism than shoehorning paeans to country into his ads, but then, I'm not on the ground in PA.
