Cas Mudde holds a PhD from Leiden University and is currently the Hampton and Esther Boswell Distinguished University Professor of Political Science at DePauw University. His most recent book, Populist Radical Right Parties in Europe (Cambridge University Press, 2007), won the Stein Rokkan Prize and was named a Choice Outstanding Academic Title in 2008. Cristóbal Rovira Kaltwasser holds a PhD from the Humboldt University of Berlin, has worked for the United Nations Development Programme (UNDP) and was a postdoctoral fellow at the Social Science Research Center Berlin (WZB). He is the recipient of the Marie Curie Intra-European Fellowship for a two-year research project on populism in Europe and Latin America, which he is currently undertaking at the University of Sussex. His research interests include populism, democracy and Latin American politics and his work has been published in Democratization and the Latin American Research Review, among others.

'Mudde and Rovira Kaltwasser's volume makes conceptual and empirical headway on what is difficult terrain. They sensibly define populism as a 'thin-centered' ideology, more akin to a political style that finds highly diverse empirical expressions in conjunction with varying specific circumstances and 'thick' beliefs about the correct social and political order. The editors have done a great job assembling a set of case studies with just the right variance to speak to the theoretical question they put front and center, namely the differential consequences of populism for democratic participation and contestation.'
