The differential impact of EU attitudes on voting behaviour in the European parliamentary elections 2019

EU attitudes are multidimensional and likely to matter differentially for voting across different parties. The 2019 European Parliament (EP) elections offer a unique setting for testing the differential effects of multidimensional EU attitudes, as the election results entailed increased political fragmentation – with notable pro- and anti-EU party groups in the EP gaining strength. This article examines the importance of EU attitudes on electoral choice and zooms in on the influence of specific EU attitudes on party voting in EP elections ('EU issue voting'). We use original survey data collected around the 2019 EP elections in ten EU member states, which include a fine-grained measurement of EU attitudes. We find evidence for EU issue voting in all countries, albeit not equally structured across countries. EU issue voting matters across all party groups with affective and performance evaluations having the strongest effects.
