I am a political scientist studying political behavior in American politics, with particular interest in how geography and group identity structure political behavior. My work investigates the behavioral consequences of geographic partisan polarization: how living in increasingly homogeneous partisan environments influences voters’ political affiliations, attitudes, and civic engagement. To this end, I develop data on the partisan residential exposure of every voter in the United States over the past decade, leveraging precise information on each voter’s residential location, partisan affiliation, and political behavior. With these data I present new evidence on the extent and causes of partisan sorting in the United States and test new theories of how where Democrats and Republicans live in relation to one another influences political behavior.
