Cleavages in Party Competition in Central and Eastern Europe

Abstract

While party system volatility remains high in Central and Eastern Europe (CEE), less is known about whether electoral competition has become programmatically structured. This paper examines the extent and evolution of programmatic differentiation across four CEE countries, Hungary, Latvia, Poland, and Romania, between the 1990s and 2023. Relying on quantitative content analysis of newspaper coverage during parliamentary election campaigns, it investigates system-level trends in programmatic competition, issue salience, and politicization, as well as party-level patterns of issue salience and entrepreneurship. The results show that programmatic competition is substantial and relatively stable over time, but varies across countries depending on historical legacies and regime trajectories. Cultural conflicts have gained importance, particularly under democratic backsliding. While established parties exhibit routinized and distinct programmatic profiles, new parties expand the issue agenda by politicizing less emphasized conflicts. The findings underscore the continued relevance of cleavage theory for understanding party competition in post-communist Europe.
