This graduate seminar surveys the frontier of the most exciting research problems in the study of American political behavior. In this course, students will critically evaluate a combination of seminal research in the field and cutting-edge work conducted recently that responds to empirical and theoretical gaps left behind by the classics. Students will use the literature, as well as their own novel research ideas, to answer questions that fundamentally shape how we think about American politics. These questions include, but are not limited to: What is party identification and why does it matter? How do voters choose a candidate? Why do some people vote and actively engage in politics, while others do not? How much do Americans know about politics? How much do Americans need to know to effectively participate in politics? How do social identities including race, ethnicity, gender, religion, and partisanship structure our political preferences?
