Party Transformation in Congressional Primaries: Faction and Ideology in the Twenty-First Century

The process through which candidates run for Congress has fundamentally changed in the twenty-first century. These new dynamics of primary competition have contributed to party transformation in Congress. Though many believe that primaries contribute to polarization, this book shows that primary voters do not systematically prefer non-centrist candidates. Instead, primaries contribute to party change by incentivizing candidates to adapt their positions between and within election cycles. Chapters identify influential groups in party networks and candidate misperceptions about primary voter preferences as key drivers of party transformation. These findings help readers to challenge common beliefs about the role of primary voters, understand the institutions, processes, and actors responsible for increasing partisan conflict on Capitol Hill, and reassess the relationship between intra-party factionalism and congressional polarization in the modern era. This book is a must-read for anyone interested in the inner workings of American politics and the forces shaping our democracy today.
