Primed by the Euro: The Impact of a Referendum Campaign on Public Opinion and Evaluations of Government and Political Leaders

Abstract

The premise of political priming is that public evaluations of political leaders are made on the basis of issues that are on the top of citizens’ minds. This study investigated the impact of a national referendum campaign about a European integration issue on the evaluation of the incumbent government, the prime minister, and the opposition leaders. Drawing on a content analysis of news media and a two‐wave panel survey, the results showed that as the topic of the referendum (the introduction of the euro) became more visible in the media during the campaign the importance of the euro issue for formulating general evaluations of political leaders increased. The incumbent government that was seen to handle the referendum poorly was penalized by the referendum. Exposure to news media outlets that covered the referendum extensively and offered negative evaluations of political leaders boosted the decline in the overall performance rating of political leaders by politically less involved respondents. These results stress the necessity of considering the campaign and the specific content of the media to understand fluctuations in public opinion during a referendum campaign. The study concludes with a discussion of the implications of a referendum campaign for political leaders.
