Whether denounced as a source of migration and diluted national sovereignty, or an anti-social carrier of austerity, the European Union is berated by European populists of diverse kinds. Support for or opposition to European integration has been extensively studied by past works, which generally contend that views of European integration are deeply related to the ideological outlooks of partisan actors. A partisan ideological view of economic exchange and regulation, international cooperation, and treatment of otherness provide the basic building blocks that ultimately structure views of European integration. This paper addresses the interplay between the historical structuring of European integration views in the context of populist partisan challenge. Using 20 years of data from the Chapel Hill Expert Surveys combined with data measuring populism, this paper argues that the distrust of traditional political elites has come to channel the ideological structure of European integration support both among populist and traditional mainstream political forces.
