Scholars have developed a large body of knowledge on the domestic underpinnings and effects of European integration. Students of the European Union (EU) have devoted considerable attention to the sources of citizen and party support for EU membership. This attention would suggest the presence of a dynamic process in which parties compete for votes by adopting stances on the EU, and citizens vote on the European issue. Evidence from the three new member states—Austria, Finland, and Sweden—shows that citizen attitudes about the EU affected vote choice in national elections in all three states before and after accession. This finding suggests the existence of an electoral dynamic between voters and parties over European integration, with mass publics hav-ing an important role in constraining future efforts at integration. Implications and directions for future research are discussed
