7. Party System Transformation and the Structure of Political Cleavages in Austria, Belgium, the Netherlands, and Switzerland, 1967–2019

Abstract

This paper combines post-electoral surveys to study the transformation of the structure of political cleavages in Austria, Belgium, the Netherlands, and Switzerland over the last five decades. Despite their history of linguistic, regional, and religious conflicts, all four countries share a common tradition of consensus decision-making, which has remained until the present. Yet, the weakening of historical cleavages, the emergence of new political formations (i.e. Green parties on the left and anti-immigration parties on the right), and the rise of new divides have significantly transformed their party systems since the 1980s. Support for green and left-wing parties among highest-educated voters, and for anti-immigration parties among the lower-educated has grown, while top-income earners have remained instead more supportive of the traditional right. Both the rise of new green and anti-immigration parties, but also changes within old parties have thus led to the emergence of multi-elite party systems, as it has been shown in other Western democracies.
