The Thursday night telecast was seen by 6.5 million viewers, and received a 1.7 rating in the adult demo. That's the largest audience for the show since December, 2005, when Oprah Winfrey appeared. "Late Show" also topped Jay Leno's "Tonight Show" (4.6 million viewers) by 43%. "Can I give you an answer?" says McCain when ribbed about his previous appearance cancellation. "I screwed up." Last night marked McCain's 14th appearance on the show. The host and candidated talked foreign affairs, William Ayers, Tina Fey and Sarah Palin. McCain confirmed that Palin was going to appear on NBC's "Saturday Night Live" this week.
