Ambivalent or indifferent? Reconsidering the structure of EU public opinion

In the US context, research on ambivalence has established that individuals often simultaneously possess positive and negative considerations on a political object. Yet little is known about ambivalence in support for European integration. This article proposes a measure that distinguishes ambivalence from indifference in attitudes towards the European Union (EU). Using data from Eurobarometer wave 63.4 and the Chapel Hill expert survey I find that the causal logics of ambivalence and indifference are sharply different. Multinomial regression analysis reveals that levels of ambivalence towards the EU increase with political sophistication. Also, citizens are more ambivalent, less indifferent, and less positive about the EU when elite division on European integration is more pronounced. Finally, trust in EU institutions and attachment to Europe decrease indifference and ambivalence about the EU.
