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.

If absolute power corrupts absolutely, does absolute powerlessness make you pure?

I'd always loved radio. I loved Bob And Ray. I loved Stan Freberg.

The theater business is very much about "Hey, if you want our big blockbuster at Christmas time, you'll play our piece of crap in April."

I've been doing Nixon pretty much my whole professional life. I was in this comedy group called the Credibility Gap in Los Angeles when he was president. I was doing Nixon on the radio, and when we did live shows I physicalized him - if that's a word - for the first time. And then I did a Nixon sketch on a very short-lived NBC show called Sunday Best.

I have a very strong visual memory of the first time I made him laugh. That was remarkable. I was like, "Oh, God, I just made Jack Benny laugh."

I think Nixon says a lot about those times. It was possibly hard, in the '90s and early 2000s to understand the grip of fear that communism had on the country in the 1950s and 1960s - a fear Nixon rode like a endless great wave on the Pacific to high office. I'm sure, though there's no evidence of it, one of the things that rankled him down deep was that it was called McCarthyism and not Nixonism.
