It doesn't have anything to do with the issues, because soundbites rarely do, but I predict their little "didn't get our jokes" moment will get the most airtime. It plays in Palin's favor since she cracked the joke, but I think it humanized both of them. It was a good a moment, and I tip my hat to Palin for that.
Now, Palin's "her reward is in heaven" phrase -- wag of the finger, I think. But that's a subject for another time.
