During the past few months several important academic articles dealing with EU attitudes and support were published. In this post I will briefly review the most important insights from these studies:
First, attitudes towards the European Union are multidimensional. This means that whether you trust the European Parliament for example is not strongly related to some other opinion on European integration like whether you perceive the EU as a threat to national identity. A survey in the Netherlands (2008) reveals five separate dimensions of EU attitudes – negative affection, identity, performance, utilitarianism, and strengthening the EU .
As a result, several different factors relate to anti-EU voting in EP elections – assessment of the democratic deficit, low perceived utility of the EU, negative affection, opposition to EU integration, and the absence of EU identity . This is an important finding because it shows that voting in EU elections is not related only to national concerns and satisfaction with the national government, and because it identifies several different aspects of EU attitudes that matter.
Similarly, specific issue concerns rather than general dissatisfaction with the EU or national governments explain the No votes in the French and Dutch referenda on the ill-fated EU Constitution . Hence, voter attitudes towards the Constitution are multidimensional as well.
Second, group identity considerations affect strongly hostility towards the EU . Attitudes towards immigrants are the most important predictors of Euroscepticism in Ireland and the Netherlands . While how religious you are is not systematically related to your assessment of the EU, religious intolerance and negative feelings towards Islam increase Euroscepticism (in the Netherlands, and to a lesser extent in Ireland) . Negative feelings towards immigrants (in NL) and religious intolerance (in Ireland) explain opposition to Turkey’s membership of the EU as well .
The importance of identity and the fear of economic migration, however, differs across the members of the EU. In wealthy states economic xenophobia matters more than in poor states, and for the high net-contributors to the EU budget the negative effects of exclusive national identity are greater .
So perhaps not surprisingly, EU contestation exists mostly in the realm of identity politics (during the last EP election campaign at least) . Election and referendum campaigns matter because they emphasize certain issues and aspects of EU integration over others, thus priming the voters . Right wing parties are the ones more likely to bring identity concerns during the election campaigns and countries with more Eurosceptic parties are more likely to put attention to EU issues . But when the campaign environment is intense, party messages matter less to the voters .
In summary, from the many dimensions of EU attitudes that are important for how you assess and vote on EU issues, identity (and the related fear of immigrants) is one of the most important and the one that is the most likely to get politicized , mostly by right-wing and Eurosceptic parties.
