If you actually watch the debate, you can see the audience shift from their initial position to their final one. I don't buy your premise that the outcome is predetermined based on the political bias you've implied with your comments.
I'm simply observing that if you look at the history of these debates, there's a pretty coherent ideology to the winning side. That's all. Make of it what you will. If I got to bet on this debate before it occurred, I'd have put all my money on the "against the mainstream media" square, and then taken out a loan to get more money to put down.
