I study political behavior with psychology, communication, and history. My book with Don Kinder on the scarcity of mass ideology is forthcoming (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 others.
My next book on partisanship & violence in the American Civil War will be complete in 2017. Related projects investigate how violent metaphors and aggressive traits shape modern political behavior (e.g. partisan polarization, voter turnout). In other media studies, I test flag imagery effects on voting, race frames in election news, and news-seeking during wartime.
