McCain essentially called Romney a liar to his face. He said(operating from notes and not a transcript): “You’ve been trying to fool people about your record. I don’t want you to try to fool people about mine.” Romney didn’t really respond or even register any emotion. That in a nutshell is his greatest weakness. Great politicians listen and react in a way that offers a sense of their own emotional wiring and character. Romney doesn’t do that and it is a problem we’ve seen more than once in these debates and in his failure to connect in big speeches.
