The politicization of European integration and support for restrictive migration policies

Why do individuals in Central and Eastern Europe support parties and candidates that hold restrictive positions on migration? I argue that the mobilization of public opinion against the European integration of external migration management is a cause. To test, I employ an experiment in Slovakia that combines a between-subjects experiment with a candidate-choice conjoint. Results indicate strong support for restrictive migration policies generally and that ideology moderates reactions to messages about European Union influence. In response to these messages, liberals shift toward restrictive policy preferences; conservatives do not. These differential effects suggest that messages about European Union influence run up against ceiling effects, where entrenched anti-migration preferences prevent attitudinal change. This paper identifies the limited set of conditions under which the mobilization of public opinion against European integration influences attitudes and electoral preferences.
