Radical American Partisanship: Mapping Violent Hostility, Its Causes, and the Consequences for Democracy

This book, written by Nathan P. Kalmoe and Lilliana Mason, explores the increasing radical partisanship in the United States.

Through a series of surveys and experiments conducted over four years, the authors provide new evidence and insights from history, psychology, and political science to contextualize the current partisan divisions.

The book examines the scope of the problem, identifies who radical partisans are, and analyzes trends over time.

It also investigates the conditions that justify violence and how elections, political violence, and messages from leaders influence radical views.

The authors find that ordinary partisanship is more dangerous than previously recognized but also see opportunities to address democratic threats and create a more inclusive politics.
