Any book is a product not only of the author's own efforts, but also of the insights and support he has received from others. Although I am responsible for any deficiencies, I have been assisted, directly or indirectly, by many teachers and colleagues in political science, particularly Stanley Feingold, Mark Ferber, Stanley Kelley, and David Truman. The resources of the New York Public Library and the editorial encouragement of Robert Erwin have been invaluable. Interviews with Governor Robert Meyner and Edward Costikyan were very enlightening. I also have been personally heartened by the encouragement of many students, friends and relatives. Finally, I have been aided by the members of my own family caucus--my favorite sons, Marc and David, and my first lady, Marlene, who has provided unequaled labor, humor, and devotion.
