I study political behavior with communication, psychology, and history. My book with Don Kinder on the scarcity of mass ideology is out May 2017 (Univ. of Chicago Press), and my articles appear in Public Opinion Quarterly, Political Communication, Political Psychology, Political Behavior, and elsewhere. My work has been featured in The New York Times, The Washington Post, The Guardian, and other news outlets.
My next book, on mass partisanship & violence in the American Civil War, will be done in 2017. Other projects experimentally investigate communication effects from violent metaphors, symbolic imagery, and racial frames, which interact with audience traits.
