Bill Kristol: "When the follow-up story in the New York press is that, in fact, New York City police chauffeured around Judith Nathan - she was Rudy Giuliani's girlfriend or mistress but certainly not yet married to him in 2000 or 2001 - that's not good either. It was a very tough week for Giuliani. I think his path to the nomination is problematic."
