Mismatch? Comparing elite and citizen polarisation on EU issues across four countries

National politicisation of European Union issues has risen following events such as the economic crisis and the refugee influx. This has led to changes at the party (rising Eurosceptic parties) and the voter level (increasing public Euroscepticism). EU politicisation is thus assumed to influence the overall distribution of EU positions in terms of EU polarisation. This raises the question to what extent there is a (mis)match between polarisation at the party and voter level, and its dependence on structural and supply-side dynamics. Using CHES 2017 data and survey data across four EU countries (Germany, Spain, Hungary and the Netherlands) this paper compares elite- and citizen-level EU polarisation. The results show a strong association of party- and citizen-level EU polarisation – for both general and policy-specific EU positions – with higher polarisation among citizens than among parties. Country-specific patterns are due to different political competition on the supply side.
