The Effect of Populist Incumbents on Democracy

Populism’s effects on democracy after populists gain control of government (hereafter, populist incumbents) are some of the best theorized and documented consequences. The argument that populist incumbents threaten institutions of democratic contestation—and, less frequently, that they correct some aspects of political participation and representation—has been made from multiple approaches.1 Scholars and commentators often cite specific cases of populists harming democracy and, since 2016, several large-N studies have confirmed their negative impact. Specifically, studies repeatedly show the harmful effects of populist incumbents on civil liberties, including media freedom, horizontal accountability, and electoral integrity in both electoral and liberal democracies. Research has been less consistent in showing the positive consequences of populist incumbents, especially for democratic representation and political participation.
