Abstract
This article reevaluates American realignment literature based on Clubb, Flanigan, and Zingale's (1980) admonition to focus on control of government and political leadership rather than electoral results. I put forward a theory of policy change in the House of Representatives which shows, like Sinclair (1977), that the effect of electoral realignments is to create a strong and unified majority party in the Congress. However, unlike other work that focuses on electoral courses, I show that structural features of elections created the new majority party in both the Civil War and the 1890s realignments. Specifically, I argue that in these two realignments a strong regional seats-to-votes distortion created the Republican majorities that enacted the policy changes associated with these realignments.
