I study political behavior with psychology, communication, 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. Related projects investigate how violent metaphors & aggressive traits mobilize & polarize modern partisans, and identify bias in state violence views. Other media studies test flag imagery effects, race frames in election news, and online news-seeking during wartime.
