"we have best health record in the world" - Mitt Romney.
Saying outright bullshit is why it's easy to appear to be victorious. Who thinks he's looking victorious? The folks watching who don't care about facts.
I think he'll look victorious among those people who don't.
The bottom line is it's very difficult to debate someone who spends the entire debate lying. Based on the optics of the debate, I thought Romney was the one who outperformed expectations. I doubt the light of morning (read: fact checkers) will be as kind to his performance though.
