UNIVERSITY OF CALIFORNIA Los Angeles The Effectiveness of Campaign Messages On Turnout and Vote Choice A dissertation submitted in partial satisfaction of the requirements for the degree Doctor of Philosophy in Political Science by Sylvia Yu Friedel 2013 ©Copyright by Sylvia Yu Friedel 2013 ABSTRACT OF THE DISSERTATION The Effectiveness of Campaign Messages On Turnout and Vote Choice by Sylvia Yu Friedel Doctor of Philosophy in Political Science University of California, Los Angeles, 2013 Professor Lynn Vavreck, Chair In this dissertation, I study campaign effects on turnout and vote choice. I analyze different campaign messages and the way they affect voters across various situations. First, through an online survey experiment, I study the impact of campaign messages and ideological cues on voters as they make inferences on candidates. Next, through a field experiment, I test whether microtargeted messages or general messages on the economy have any effect on turnout. Lastly, using online survey data, I examine how cross-pressured voters behave electorally when holding an opposing party’s position on social issues. These three studies indicate that different messages do, in fact, matter. Furthermore, voters are not fools—they are reasoning and rational. While partisanship does continue to heavily impact voting decisions, voters do consider issue positions and different voting dimensions (i.e., social, economic, moral). In light of this, campaigns should continue their efforts to persuade and inform the electorate. ii The dissertation of Sylvia Yu Friedel is approved. John Zaller David O.

I would first like to thank my committee members, Lynn Vavreck, John Zaller, David Sears, and Tim Groeling. As my mentor and dissertation chair, Lynn provided countless instances of professional guidance and academic suggestions. Her dedication to my research and career has been unquestionable. While Lynn influenced the way I thought about research puzzles and arguments, John taught me how to support those arguments with statistical findings. His simple explanations of how to interpret statistical results carried me through my graduate program. David stretched my boundaries and enabled me to consider the psychological underpinnings of political behavior. When I struggled to find a dissertation topic, his constructive criticism was immensely helpful. Finally, Tim’s background in political communication along with his encouragement shaped my research ideas. He also provided access to the Communications department’s survey pool for an online survey experiment, which provided research results that are presented in Chapter 2 of this dissertation. I would also like to thank my colleagues at UCLA: Brian Law, Carrie LeVan, Darin Dewitt, Emily Ekins, Emily Hallock, Hovannes Abramyan, James Lo, Kristen Kao, and Seth Hill. Sharing and brainstorming project ideas, editing each other’s papers, and supporting our research endeavors were regular activities, and without these, my dissertation would not be as sharp. We pushed each other to succeed especially when it seemed impossible, and for this, I will be grateful. Finally, I would like to thank my family and friends. I owe thanks to my lifelong friends, Ali, Catherine, Dan, Elysia, Michael, Rax, and my brother, Michael, for always listening, offering useful advice, and providing the mental distractions that reenergized me to continue my research. I also would like to thank my parents to whom I dedicate this dissertation. Without their open-mindedness and support, I would not be where I am today. Finally, I thank my husband Lou for his unwavering confidence in me. In the course of my graduate career at UCLA, we got married, welcomed our beloved dog Bam Bam into our lives, bought a house, and celebrated the joyous arrival of our son, Max. I have serious doubt that I could have finished this dissertation without him nor would I have had as much fun along the way. x Vita/Biographical Sketch 1999: Northern Highlands Regional High School 2003: B.S.
