Populist Polarization and Party System Institutionalization

The institutionalization of party politics is supposed to contribute to the consolidation of democracies. Analysis of Hungary’s democratic backsliding shows, however, that this is not necessarily the case. This article demonstrates that the combination of populist party strategies, polarized party relations, and the inertia of the party system constitutes a significant challenge (here labeled “populist polarization”) to the consolidation of liberal democracy. After considering the applicability of structuralist and transitologist frameworks to the political dynamics in Hungary, the article differentiates the notion of populist polarization from similar concepts and argues that populist polarization in the region poses a more acute danger to high-quality democracy than the much-feared under-institutionalized and fragmented configurations of party politics.
