Kirchheimer’s French Twist

Abstract

Despite the fact that the catch-all thesis has profoundly affected scholarship on political parties, operationalizing the thesis and applying it to evaluate empirical cases has proved challenging for scholars. The thesis has been criticized for lacking a theoretical framework of analysis and clear causal logic. Therefore, while it is often cited it is rarely tested. In this article I develop a model of the catch-all thesis and then test it in the case of France, one of the original cases specified by Otto Kirchheimer in his observations. The French case exhibits competing tendencies of party convergence and polarization with the persistence of ideology. Findings suggest some confirmation of the catch-all thesis prediction regarding bipolarization, yet not according to the rationale asserted in the thesis. Additionally, presidentialism effects prove an important explanatory factor and the 2007 elections suggest a possible catch-all party in the UMP.
