true interests. Müller also shows that, contrary to conventional wisdom, populists can govern on the basis of their claim to exclusive moral representation of the people: if populists have enough power, they will end up creating an authoritarian state that excludes all those not considered part of the proper "people." The book proposes a number of concrete strategies for how liberal democrats should best deal with populists and, in particular, how to counter their claims to speak exclusively for "the silent majority" or "the real people." Analytical, accessible, and provocative, What Is Populism? is grounded in history and draws on examples from Latin America, Europe, and the United States to define the characteristics of populism and the deeper causes of its electoral successes in our time.
