More negative when it matters less? Comparing party campaign behaviour in European and national elections

Do parties campaign differently in different circumstances? Research seems to suggest that parties do indeed engage in harsh interparty attacks and fearmongering during ‘second-order’ elections, such as European elections/elections to the European Parliament (EP), perhaps even to the same extent as during national elections. However, to the best of our knowledge, the differences in the campaign strategies used by parties in national and European elections have never been assessed systematically. In this article, we compare the content of election campaigns (negative tone, fear appeals, enthusiasm appeals) by 150+ parties across 28 countries that participated in the 2019 elections to the European Parliament and at least one national election between 2016 and 2020. Triangulating two independent expert surveys (EPEES_19 and NEGex) we show that, contrary to our expectations, parties do not use more negative campaigning during European elections. However, more extreme parties tend to use a more negative tone and fewer enthusiasm appeals during European than national elections.
