European populism before the pandemic: ideology, Euroscepticism, electoral performance, and government participation of 63 parties in 30 countries

Abstract This contribution is conceived as a resource on the state of European populist parties before the outbreak of the COVID-19 pandemic. It reports on cross-national comparative findings generated by data collected from 30 European countries as to the state of populist parties in one calendar year (2019) and provides an extensive qualitative overview of the national cases. The article shows that while populist parties are preponderantly on the right, there is a significant degree of ideological variation among European populism. The data show significant diversity in their electoral performance but also that populist party participation in government is no longer a marginal phenomenon. The article ultimately elaborates on the various types of positions on European integration – from soft/hard Euroscepticism to lack thereof – and discusses the implications of their affiliation in the European Parliament.
