What Happened to the Vital Center?

Book excerpt: Gradually, the moderating influence that parties played in structuring campaigns and the policy process eroded to the point where extreme polarization dominated and decision-making power migrated to the presidency. Weakened parties were increasingly dominated by presidents and their partnerships with social activists, leading to a gridlocked system characterized by the politics of demonization and demagoguery. Executive-centered parties more easily ignore the sorts of moderating voices that had prevailed in an earlier era. While the Republican Party is more susceptible to the dangers of populism than the Democrats, both parties are animated by a presidency-led, movement-centered vision of democracy. After tracing this history, the authors dismiss calls to return to some bygone era. .
