A Communication Model of the Impact of Presidential Candidate Character Traits on Vote Preference Abstract This dissertation presents a communication model of the impact of candidate character traits on vote preference and outlines how the communication environment surrounding US presidential elections influences the selection of salient candidate character traits, how these traits are framed by mediated communication, and reports their influence on otev preference which is dependent on voters’ level of news media use. A conceptualization of traits and the theoretical basis for how and why they may play a role in vote preference is presented and suggests traits provide an easily accessible heuristic allowing citizens to make predictions for future behavior of a candidate if elected. The theoretical foundation of the model is based on the integration of agenda-setting, priming and framing theories. The moderating role of media use on the relationship between perceptions of candidate traits and vote preference is also explicated. Support for this model is presented in three case studies that analyze three different datasets across two US elections. Specifically, the 2004 and 2008 general elections are explored using the 2004 and 2008 National Annenberg Election Studies (NAES) and an October 2008 dataset from Pew Research Center. These data provide empirical evidence supporting the theoretic argument driving this dissertation. All three case studies produce similar and consistent results and the congruence of the findings across different elections and multiple data sources contributes to the robustness and validity of the communication model of the impact of candidate character traits on vote preference offered in this dissertation.

Delli Carpini Supervisor of Dissertation ________________________________________ Dr. Katherine Sender Graduate Group Chairperson Dissertation Committee: Dr. Michael X. Delli Carpini Dr. Kathleen Hall Jamieson Dr. Joseph Cappella Dr. Richard Johnston ii ACKNOWLEDGMENTS My first research project as a graduate student at the Annenberg School for Communication at the University of Pennsylvania began with Dr. Kathleen Hall Jamieson recruiting me in her quest to examine the impact of media coverage of a 2004 Los Angeles Times poll that reported the public thought incumbent president George W. Bush was more stubborn than his Democratic challenger Senator John Kerry. Our findings from that study suggested that coverage of this poll furthered the perception that President Bush was indeed stubborn. While this initial collaboration led to a published article in a respected academic journal, it also sparked my interest in the inter- relationships among media, perception of candidate character traits, and vote choice. Five years later I offer this dissertation. I am grateful to have the Dean of the Annenberg School for Communication, Michael X. Delli Carpini, as my academic advisor and dissertation chair. Michael was generous in his guidance while at the same time unrelenting in his challenging and questioning of my theoretical and analytical thinking which has had a profound impact on this dissertation and, more importantly, how I will approach communication research in the future. As a scholar of character traits, I believe that I am qualified to categorically state that Michael has the best character traits that an advisee could ask for in a dissertation advisor. I am also grateful to Drs. Joseph Cappella and Richard Johnston who served on my dissertation committee. Dr. Cappella‘s graduate classes in the Annenberg School for Communication were instrumental in my understanding in how to develop an advanced iii communication theory and synthesize disparate findings from diverse research areas. Dr. Johnston‘s graduate class on Public Opinion and Elections provided a solid theoretical grounding in past and current political science literature on U.S. presidential elections. I have learned much from Richard as the co-director of the 2008 National Annenberg Election Study where I held minor role on the 2008 NAES team. On many occasions, both distinguished professors have provided invaluable insight that has contributed, in multiple ways, to the completion of this dissertation. I am extremely indebted to Dr. Kathleen Hall Jamieson. She has been a great friend and an even greater mentor. We have worked closely together over the past five years and her profound influence is apparent in my scholarly endeavors. I have learned so much from her on so many levels that typed words could never fully capture the impact that she has had on me as a scholar, teacher, and person. My friends in the Annenberg School for Communication must be acknowledged. For four years my office mates, Cabral Bigman and Mike Serazio, have been great sounding boards, offered critical perspectives, provided unwavering support, and most importantly provided many laughs. Without them my time at Annenberg would not have been such a joy. The same must be said of my friend and Annenberg colleague, Shawnika Hull. Our conversations on the latest communication research advancements and methodological approaches greatly influenced my thinking when approaching the research questions outlined in this dissertation. Not only was NAES managing director, Ken Winneg instrumental in the success of the 2004 and 2008 surveys that provide the bulk of the data analyzed in this iv dissertation, he has also been a great colleague and friend throughout my time at the Annenberg Public Policy Center. I am also indebted to my fellow graduate students on the National Annenberg Election Survey Team—Emily Thorson, Susanna Dilliplane, Jeff Gottfried, and Seth Goldman. Many friends at the Annenberg Public Policy Center have been extremely supportive throughout this process and I am proud to be a part of such a great community. I am deeply indebted to my best friend and wife Jodi and my beautiful daughters Eva and Stella for their unwavering support. Words cannot describe the love and happiness that they bring me. v ABSTRACT A COMMUNICATION MODEL OF THE IMPACT OF PRESIDENTIAL CANDIDATE CHARACTER TRAITS ON VOTE PREFERENCE Bruce W. Hardy Michael X.
