Populism and Protest Intensity: A Cross-National Analysis

Populist studies are increasingly interested in the effects that populism has on the politics of contemporary democratic systems. This article analyzes the relationship between populist parties and politicians and the intensity of political protest. Arguing that populists generate feelings of anger and outrage at establishment politicians, develop close relationships with social movements, and instigate further polarization and resistance from the opposition, the existence of populist actors in a political system is believed to generate more political protests. Using a unique dataset of populist parties in European, Latin American, and North American countries, cross-national testing demonstrates strong positive correlations between the presence of populists in power and anti-government demonstrations, testifying to the effect that populists have on protest activity. Tests for the existence of populist parties in the opposition, however, reveal no empirical support for increased levels of political protest, implying that the strongest effect only comes once populists come to power. These results provide necessary nuance to our understanding of the destabilizing effects of populism and its consequences for contemporary liberal democracies.
