Wedge-issue dynamics and party position shifts

Abstract

Even when the stakes of party-building are high, political parties often find their members divided over a key policy position. In post-Reconstruction America, the hot-button issue of excluding Chinese immigrant workers strengthened Democratic cohesion while splitting the ‘party of Lincoln’. Previous research has not completely investigated the role of party competition and cohesiveness in paving the way for passage of the Chinese exclusion laws. In this investigation of the legislative politics of banning the Chinese from 1879 to 1882, it is found that cross-pressured members sometimes facilitate party transformation. The evidence demonstrates that partisan responses to potential wedge issues are a previously unnoticed source of explanation of eventual party position changes.
