Investigating Visual Content Shared over Twitter during the 2019 EU Parliamentary Election Campaign

Political communication increasingly takes on visual forms. Yet, despite their ubiquity in everyday communication and digital campaigning, the use of these visuals remains critically understudied. In this article, we investigate the formats and modes of visual content deployed by Twitter users over a two-week period leading up to the 2019 EU Parliamentary elections and across two publics: those discussing the election at large and those discussing the more contentious issue of EU membership. Conducting a multilingual, cross-comparative content and thematic analysis of a sample of 1,097 images, we find that: (1) Visuals originating from traditional political actors prevailed among both Twitter discourses; (2) users shared substantial amounts of anti-EU, populist and, to a lesser extent, extremist images, though this content remained largely disjointed from the mainstream public debate; and (3) political humor emerged as a vector for anti-establishment and Eurosceptic themes, especially in discussions critical of the European project. We discuss the implications of our findings for the study of visual political communication and social media manipulation.
