All my life I have been passionately interested in monomaniacs of any kind, people carried away by a single idea. The more one limits oneself, the closer one is to the infinite; these people, as unworldly as they seem, burrow like termites into their own particular material to construct, in miniature, a strange and utterly individual image of the world.
I don't know if there's any secret recipe. Just a lot of hard work. Pay attention to your constituents. I always had a great Iowa staff that did all my great constituent service work. And I found that people would forgive me for a lot of my "liberal sins" because I paid attention to the home front.
