By Peter K. Enns

I have published three books: Hijacking the Agenda (with Chris Witko, Nate Kelly and Jana Morgan), Incarceration Nation, and Who Gets Represented? (edited with Chris Wlezien). All three books seek to better understand political representation, inequality, and social outcomes in the United States.
