Issue Salience in the European Parliament Election: An Analysis of Economic, Environmental and Immigration Issues on Social Media

Abstract This study investigates under what conditions Members of the European Parliament (MEPs) emphasised relevant policy issues—economy, climate/environment and immigration—during the 2019 European Parliament election campaign. Building on research on issue salience in EP elections and based on the content published on X/Twitter by MEPs in the weeks preceding the election, the study identifies key drivers of issue attention. It shows that issue relevance in the domestic public agenda and individual issue expertise increase MEPs' attention to the three policy issues, whereas parties' stance on the sociocultural dimension only affects attention to climate/environment. The study contributes to research on issue salience in EP election campaigns and MEPs' communication on social media, highlighting the importance of adopting a cross‐issue approach when studying European elections.
