John Kerry can be absolutely ruthless. I would not want to be on his enemies list when he's ready to go after you.

When I was 8 years old, I made my own encyclopedia of American biography - Johnny Appleseed, Jim Bowie, Davy Crockett, Daniel Boone, Charles Lindbergh, my pantheon of favorite heroes. Then I would write my own things and sew them together and try to make my own book.

Forget politics. The real story is the advancements being made in medicine. We're on the verge of conquering cancer and Alzheimer's and numerous other diseases. The DNA revolution has just begun. Scientific advancement usually trumps politics.

I have a lot of books I want to write.

John Kerry wants to be the hero in his own drama. He likes King Arthur and the Round Table. He likes the young swashbuckling Churchill, and he loved the early antics of Theodore Roosevelt.

I think there's a green side to John Kerry, if you like, that he's an environmental activist. His record on the environment is as best as you have on a pro-environment record of anybody in the U.S. Senate.
