IN WRITING THIS BOOK I benefited from a great deal of help, and it is a pleasure to acknowledge those who provided assistance.
I received very good help in compiling information from Brett Curry, Joe Lyons, and Karen Swenson. Their work provided much of the raw material that I use, and that material also helped me in developing the lines of argument that are presented here.
The book incorporates research I have done in collaboration with Corey Ditslear on the selection of Supreme Court clerks and with Lori Hausegger on the relationship between the Supreme Court and Congress. I appreciate their allowing me to use that research, and I also appreciate the insights I gained from working with them. Brandon Bartels shared with me the data he collected on salient Supreme Court cases, data used in some analyses in chapter 5.
A number of professional colleagues provided ideas, reactions, and sources on topics. They include Brandon Bartels, Brad Canon, Howard Gillman, Mark Graber, Clarissa Hayward, Randy Hodson, Ted Hopf, Kent Jennings, Jon Keller, Dean Lacy, Tom Nelson, John Parrish, Jim Pfiffner, Kira Sanbonmatsu, Jeff Segal, Don Sylvan, and Herb Weisberg. Lew Bateman gave me useful ideas and encouragement for development of the book. Roy Flemming and Lynn Mather each offered a number of helpful ideas about issues that I address. Mike MacKuen and Randy Schweller made very helpful suggestions for empirical inquiries that I then pursued. I presented parts of the book's arguments and evidence in seminars at Texas Tech University, the University of New Orleans, the University of North Carolina at Chapel Hill, and the University of North Texas. Comments and suggestions at those seminars were quite useful.
Jim Brudney and Bob Arkin read and commented on parts of the manuscript on which they have special expertise. Lori Hausegger and David Klein read each chapter and provided long lists of helpful ideas. I appreciate their very substantial contributions. The anonymous reviewers of the manuscript for Princeton University Press made insightful comments that improved the book considerably.
I received valuable assistance from the people I worked with at the Press. I appreciate all the help that Mark Bellis, Jennifer Nippins, and Richard Isomaki gave me. Chuck Myers did a great deal to make this book possible, and I am very glad that I have had the opportunity to work with him.
I have already thanked a number of colleagues at Ohio State University for their contributions. I owe more general thanks to my colleagues for
