I couldn't help but be struck that this guy I had thought was the embodiment of everything wrong with American politics, a lot of his domestic policy was mind-numbingly, head-spinningly to the left of Obama's. It was under Nixon that the EPA was created. It was under Nixon that OSHA was created. Under Nixon that the Clean Air and Clean Water Acts were passed.

You can get an awful lot of effects into the customer's mind for a great deal less time and money in radio than you can in television.

I just think everyone knows you go on those [political satire] shows if you're a politician to, "humanize yourself" - to show, "Hey, I can take a joke." Well, why should satire be in the service of humanizing these people who are supposed to be the target of our venom and vitriol? I think that's unseemly.

Nixon's genius was that he was able to portray himself as the toughest of the anti-communists, and yet run on a platform that he had a plan to end the Vietnam War. And, of course, his plan was to prolong it until his second election - but he didn't tell us that then.

I'm not sure that there's anybody else that's as psychologically complex and who's given us this window into his soul that Nixon gave us. That's what I find absolutely addictive and seductive.

I think the British learn their history through the prism of this gallery of grotesques known as the royals.

When I was growing up, we learned our history almost as lives of the saints. And it came as a shock, "Oh, Jefferson had slaves?" It always comes as a shock to us that elevation to the White House didn't somehow cleanse them of all their deep character flaws.
