Thomsen, Danielle M. 2017. Opting Out of Congress: Partisan Polarization and the Decline of Moderate Candidates. New York: Cambridge University Press.
- Scholars have focused on mass-level and institutional-level explanations for the rise in partisan polarization in the U.S. Congress. My book instead examines ideological changes in the candidates who run for Congress. The central argument is that moderates are opting out of the congressional candidate pool, further exacerbating the ideological gulf between the parties in Congress. Liberal Republicans and conservative Democrats are outsiders in both parties, and the personal and professional benefits of congressional service are too low for them to run. Although the political center has long been deemed a coveted position in the legislature, it is now an increasingly lonely and lowly place to be. The focus on the supply of congressional candidates sheds light on why polarization has continued to grow unabated and why recent policy reforms have been largely ineffective to date.
