OF PRIMARY IMPORTANCE: AMERICAN PRIMARY ELECTIONS 1945–2012 Thesis by J. Andrew Sinclair In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy California Institute of Technology Pasadena, California 2013 (Defended May 10, 2013) ii © 2013 J. Andrew Sinclair All Rights Reserved iii Acknowledgements I would like to thank the members of my committee for their aid and advice: Dr. D. Roderick Kiewiet, Dr. Christian Grose, Dr. Philip Hoffman, Dr. Jean-Laurent Rosenthal, and Dr. R. Michael Alvarez. In particular, I would like to thank Dr. Alvarez for not growing weary of Sinclairs (of one kind or another) pestering him in his office over the last dozen years. Pieces of the analysis here could not have been accomplished without the aid of my classmates Thomas Ruchti and Peter Foley; fellow students Allyson Pellissier, Jackie Kimble, Federico Tadei, and Andi Bui Kanady made helpful suggestions and comments as well. Jeffery Wagner, Olivia Schlueter-Corey, and Madeleine Gysi helped collect and organize the data required for the multi-state analysis. Ryan Hutchison helped put me in contact with former State Senator and Lt. Governor Abel Maldonado. Dr. Morgan Kousser helpfully directed me to the Los Angeles Law Library. Dr. Jonathan Nagler and Dr. Alvarez provided helpful advice on the 2012 survey; the James Irvine Foundation provided generous funding for that research. Elissa Gysi provided very helpful advice for conducting the legal research; she also agreed to marry and tolerate the author as books piled up around the apartment. I would also like to thank my parents, Dr. J. Stephen Sinclair and Joan Sinclair, for… a list too long to enumerate. This work also owes a great deal to both of my sisters, Dr. Betsy Sinclair and Dr. Laura Sinclair, for lighting the way to Caltech. iv Abstract American non-presidential primary elections remain an understudied, but very important, part of our political process. In this study, I examine the state of the political science literature and provide two main contributions. First, I describe in detail all of the primary election laws used across the United States from 1945 to 2012 and analyze the consequences of using one kind of law over another. I find that, contrary to expectations, closed primary rules may result in more competitive primary elections than open primaries; furthermore, states with closed primary rules appear to get more moderate representation on average in the U.S. Senate. Due to changing legal standards, more states may be more likely to adopt in the future a “top-two” primary system which California used for the first time in 2012. I also analyze the first implementation of the “top-two.” Proponents of the new law suggested that it would help elect more pragmatic legislators. I find, though a unique survey of California voters, that they sometimes achieved their goal. v Table of Contents Acknowledgements - - - - - - - - iii Abstract - - - - - - - - - iv List of Tables and Figures - - - - - - - vi Introduction - - - - - - - - - 1 Chapter 1: Primaries in Political Science - - - - - 10 Chapter 2: State Laws, 1945–2012 - - - - - - 52 Chapter 3: Laws, Competitiveness, and Representation - - - 148 Chapter 4: A Peek Into the Future: 2012 California Survey - - - 178 Chapter 5: Voter Behavior in California’s 2012 Top-Two Primary - - 247 Concluding Remarks - - - - - - - - 307 References - - - - - - - - - 311 vi Tables and Figures Fig. 2-1 - - - - - - - - - 104 Massachusetts Party Enrollment Fig. 2-2 - - - - - - - - - 111 Nebraska Sample Ballot Fig. 3-1 - - - - - - - - - 152 Margins of Victory 1968–2012 Fig. 3-2 - - - - - - - - - 153 Distribution: Percent Margin of Victory Fig. 3-3 - - - - - - - - - 154 Types of Primary Laws Used 1946–2012 Tab. 3-1 - - - - - - - - - 158 Margin of Victory and Primary Type Tab. 3-2 - - - - - - - - - 160 Regression: Top of the Ticket, Margin of Victory, Narrow Categories Fig. 3-4 - - - - - - - - - 162 Margin of Victory and Per Capita Income Tab. 3-3 - - - - - - - - - 163 Regression: Top of the Ticket, Margin of Victory, Broad Categories Tab. 3-4 - - - - - - - - - 164 Regression: U.S. Senate Only, Margin of Victory Tab. 3-5 - - - - - - - - - 166 Regression: Top of the Ticket, Margin of Victory, Open Seats Only Tab. 3-6 - - - - - - - - - 167 Regression: Top of the Ticket, Margin of Victory, Logit Fig. 3-5 - - - - - - - - - 170 U.S. Senate, Average Ideological Distance Fig. 3-6 - - - - - - - - - 170 Distribution of State Mean Ideological Distances vii Tab. 3-7 - - - - - - - - - 172 Regression: Average Ideological Distances, Broad Open Category Tab. 3-8 - - - - - - - - - 173 Regression: Average Ideological Distances, Anti-Party Category Tab. 3-9 - - - - - - - - - 174 Regression: Average Ideological Distances, Narrow Categories Tab.
