European Solidarity Takes the Field: The Dimensional Structure of Political Competition in the European Union After the Polycrisis

Most studies investigating the dimensionality of political space in Europe demonstrate that European Union (EU)‐related issues are orthogonal to the economic left–right dimension. This literature usually employs survey items tapping into general support for the EU. However, the multiple crises that hit Europe after 2008 have polarized even Europhile voters on the more specific issue of European solidarity. This article aims to investigate how voters' attitudes towards European solidarity interplay with their position on the left–right and European integration dimensions, as well as specific economic and cultural issues. Empirical analyses employ original survey data collected in 2019 in 10 EU countries. Results partially support the expectations of regional differences in the dimensionality of the political space, with European solidarity more strongly associated with left–right, EU integration and immigration in Northern EU member states than in Eastern and Southern countries, in which voters are more likely to support solidarity notwithstanding their general political orientations.
