About the author
German political theorist (b. 1970), professor of politics at Princeton University. A scholar of democracy, constitutionalism, and the history of political thought, Müller writes for both academic and public audiences; What Is Populism? became one of the most cited short works on the global populist surge.
Synopsis
Müller distinguishes populism from ordinary democratic politics by its moralized, exclusive claim to represent a singular, authentic people against corrupt elites and undeserving outsiders. He examines how populists govern (capturing the state, mass clientelism, suppressing civil society while claiming to act for the people), why populism is a permanent shadow of representative democracy, and how democrats should respond — by engaging populists' supporters without adopting their anti-pluralism.
Core passage idea
Paraphrase · Modern copyrighted workMüller argues that what defines populists is not merely criticism of elites but a claim that they alone represent the 'real people' — a moralized anti-pluralism that casts all opponents as illegitimate.
By locating populism's danger in its anti-pluralism rather than its anti-elitism, Müller separates legitimate democratic protest from the claim to be the people's sole voice. The distinction clarifies why populism, so defined, sits uneasily with constitutional democracy.
To avoid a bubble
Pair with theorists who see populism more favorably — as a needed corrective to unresponsive elites or a route to democratic renewal (Laclau, Mouffe) — and with critics who find Müller's definition too narrow or too quick to delegitimize popular movements.
Reading note
Short and clarifying. Read it as the analytic anchor for debates over populism, alongside more sympathetic accounts (Laclau, Mouffe) and the democratic-backsliding literature (Levitsky and Ziblatt).
