Does Left/Right Structure Party Positions on European Integration?

Abstract

How is contestation on European integration structured among national political parties? Are issues arising from European integration assimilated into existing dimensions of domestic contestation? We show that there is a strong relationship between the conventional left/right dimension and party positioning on European integration. However, the most powerful source of variation in party support is the new politics dimension, ranging from Green/alternative/libertarian to Traditional/authoritarian/nationalist.
