Recent studies have shown that the most important factor explaining opinions on European Union issues is attitudes towards immigrants. Two arguments are given to explain this effect. We contend that these arguments are both built on the idea that people with anti-immigrant attitudes frame other Europeans as an out-group. We then test the validity of these arguments by measuring how respondents in a voter survey frame the issue of Turkish membership. We find that framing the issue in terms of out-groups indeed mediates the effect of anti-immigrant attitudes on support for Turkish membership. This finding offers new insights into why levels of public support vary over different EU issues, because opposition is likely to increase when an issue is more easily framed in terms of out-groups.

Previous studies predicted European Union attitudes using anti-immigrant attitudes, but without explicitly accounting for attitudes toward different out-groups. We propose that group-specific attitudes independently predict attitudes toward the European Union, but only when the out-group is linked to the European Union issue in question. We additionally argue that realistic or symbolic threat associated with specific out-groups determines whether utilitarian or identity considerations are more important in predicting European Union attitudes. Using a nationally representative Dutch sample (N = 2347), we focus on attitudes toward Polish and Muslim immigrants to predict strengthening of European Union integration and Turkey’s potential accession and find support for our hypotheses. The findings indicate the need to rethink the relationship between out-group perceptions and European Union attitudes.

The 2014 European Parliament (EP) elections were held after a period where public opinion about the EU changed significantly. In this paper we investigate evaluations of the performance of the European Union, as this dimension of EU attitudes is particularly relevant ahead of elections. We look at public opinion developments since 2009 and then zoom in on the role played by the news media in shaping public opinion about EU performance by linking citizens’ evaluations across time to the news media content they were exposed to. The article relies on original multiple wave survey panel data and a systematic media content analysis in the Netherlands. It shows how public opinion has changed, how it changes around EP elections, and how exposure to media coverage can help improve citizens’ evaluations of EU performance.
