Abstract

As populist parties and politicians have grown in prominence in democracies, scholars have turned their attention to the causes, and consequences, of populist attitudes among citizens. Some preliminary research indicates that individuals with populist attitudes are more likely to express support or tolerance for the use of violence to achieve political objectives. In this study, I examine this relationship further by investigating factors that mediate the effect of populism on endorsement of political violence. Using an original survey of more than 1300 subjects in the United States, I evaluate four elements that theoretically mediate the relationship between populism and support for political violence: economic grievances; distrust of political institutions; perception that social and demographic changes in the United States are threatening; and preferences for politically illiberal or nondemocratic rule. I find that the effect of populism on support for political violence is mediated through fear of social/demographic change and preference for illiberal rule but not through economic grievances or distrust of political institutions. Taken together, over 50% of the effect of populism on support for political violence is mediated through heightened anxiety about social and demographic changes in the U.S. and illiberal attitudes.
