Divided Government and the Rise of Social Regulation

Abstract

Political scientists have debated the causes of divided government since the Reagan administration. In addition, a handful of scholars have also pondered the possible consequences of divided party rule for politics and policy. Still, one serious oversight in the divided‘government literature is the potential consequences of divided party rule for the types of policy pursued during divided and unified party regimes. Divided government may create incentives for conflicting institutions to use social regulation debates, often considered the most divisive public policy debates, as “wedges” in order to damage the opposing party in future elections. Each party also has an incentive to embrace social regulation in order to reaffirm its allegiance to its core constituency. This article tests the hypothesis that divided government produces more important social regulation votes than unified government. I define the population of important votes as all Key Votes in the House of Representatives from 1953 to 1998. The data analysis reveals that important social regulation votes are in fact more prominent during eras of divided government than during unified party control. This finding has potential implications for the tenor of our national politics as well as the public trust.
