Do populist parties promote direct democracy? An empirical assessment in 29 countries in the last two decades

Abstract

ABSTRACT Populism is often associated with direct democracy. However, empirical support for this connection remains limited. Analysing a unique dataset on national referendums across 29 countries, this study challenges the presumption that populists are more inclined to advocate for referendums. Surprisingly, populists exhibit this tendency primarily when in opposition. Despite the increasing inclusion of populist parties in coalition governments, their impact on facilitating national-level direct democracy is more complex than anticipated. Utilising V-DEM data over 30 years, we find that populists prima facie enhance the use of direct democracy. However, this effect is contingent on contextual factors, such as party system institutionalisation and the democracy's age, indicating a nuanced relationship between populism and direct democratic practices.
