I Can do Anything Better than You Can
I don't think that there is any more air beneath the wings of the meme that Obama isn't up to the rigors of a tough campaign against the Republicans. He has out-strategized and out-organized Hillary in the past weeks, and she can't compete in charisma.
It isn't over 'til it's over, but it's approaching the point where Hillary will need a miracle or big Obama blunder to win it.
His victory speech was textbook. Without stooping to any personal attack, he sharply drew the lines between himself and Hillary and especially between himself and McCain. He lauded McCain as a hero but still managed to skewer him for his policies and his policy flipflops.
