In recent decades, the prevalence of negative communication has intensified across the world. In this article, we seek to understand the mechanisms that spread negativity about a unified Europe. We study the specific conditions under which negative party communication boosts media visibility, focusing on the role of country-specific party conflicts on European Union integration. Our analysis is based on content analysis data of parties’ press releases and media coverage in the 12 weeks preceding the 2014 European Parliamentary elections in seven (...) countries. We find that EU-negative party communication by and large does not matter for party visibility in the media, though the results provide scant evidence that cross-national differences relate to a country’s party conflict.
