Listen to the crowds in these two speeches. You only have to get about 10 seconds in to each one.
Obama:
McCain:
(Both Via Talking Points Memo.)
Obama sounds like he is surrounded by hundreds of people who are attentive to his every word. He is. McCain sounds like he’s in a little room with a dozen people behind him and another dozen behind the camera. I don’t know if he is or not, but it sure struck me as a contrast.
