Is There a Single German Party System

Few aspects of politics have been as variable as partisan politics in the two decades since German unification. In the East, citizens had to learn about democratic electoral politics and the party system from an almost completely fresh start. In the West, voters experienced a changing partisan landscape and the shifting policy positions of the established parties as they confronted the challenges of unification. This article raises the question of whether there is one party system or two in the Federal Republic. We first describe the voting results since 1990, and examine the evolving links between social milieu and the parties. Then we consider whether citizens are developing affective party ties that reflect the institutionalization of a party system and voter choice. Although there are broad similarities between electoral politics in West and East, the differences have not substantially narrowed in the past two decades.
