For whatever reason, TiVo decided to record The Early Show, so I watched McCain's interview.
It was a very good moment for him. He was strong, upbeat, and had a sense of humor. It reminded me a bit of McCain 2000.
He clearly enjoys being the underdog and I suspect if he displayed some of this behavior on the campaign trail more often, he might see some better poll numbers.

ETA links. You need to watch the videos, rather than read the transcripts, to get a real feel for what I am describing.
