A provocative exploration of how America’s democratic crisis is rooted in a dangerous mismatch between our Constitution and today’s nationalized, partisan politics.

The ground beneath American political institutions has moved, with national politics subsuming and transforming the local. As a result, American democracy is in trouble.

In this paradigm-shifting book, political scientists Paul Pierson and Eric Schickler bring a sharp new perspective to today’s challenges. Attentive to the different coalitions, interests, and incentives that define the Democratic and Republican parties, they show how contemporary polarization emerged in a rapidly nationalizing country and how it differs from polarization in past eras. In earlier periods, three key features of the political landscape—state parties, interest groups, and media—varied locally and reinforced the nation’s stark regional diversity. But this began to change in the 1960s as the two parties assumed clearer ideological identities and the power of the national government expanded, raising the stakes of conflict. Together with technological and economic change, these developments have reconfigured state parties, interest groups, and media in self-reinforcing ways. The result is that today’s polarization is self-perpetuating—and intensifying.

Partisan Nation offers a powerful caution. As a result of this polarization, America’s political system is distinctly and acutely vulnerable to an authoritarian movement emerging in the contemporary Republican Party, which has both the motive and the means to exploit America’s unusual Constitutional design. Combining the precision and acuity characteristic of their earlier work, Pierson and Schickler explain what these developments mean for American governance and democracy.

During the past decade, Democrats and Republicans each have received about fifty percent of the votes and controlled about half of the government, but this has not resulted in policy deadlock. Despite highly partisan political posturing, the policy regime has been largely moderate. Incremental, yet substantial, policy innovations such as welfare reform; deficit reduction; the North American Free Trade Agreement; and the deregulation of telecommunications, banking, and agriculture have been accompanied by such continuities as Social Security and Medicare, the maintenance of earlier immigration reforms, and the persistence of many rights-based policies, including federal affirmative action.

In Seeking the Center, twenty-one contributors analyze policy outcomes in light of the frequent alternation in power among evenly divided parties. They show how the triumph of policy moderation and the defeat of more ambitious efforts, such as health care reform, can be explained by mutually supporting economic, intellectual, and political forces. Demonstrating that the determinants of public policy become clear by probing specific issues, rather than in abstract theorizing, they restore the politics of policymaking to the forefront of the political science agenda.

A successor to Martin A. Levin and Marc K. Landy’s influential The New Politics of Public Policy (Johns Hopkins University Press, 1995), this book will be vital reading for advanced undergraduate and graduate students in political science and public policy, as well as a resource for scholars in both fields.
