Tweeting about Brussels? European governance in the communications of national parties and leaders
In this paper, I investigate whether national political parties and leaders communicate about European governance. According to the neo-functionalist argument, I expect them to emphasize European affairs at the time of important European governance events and when they are involved in European decision-making processes. I use a unique longitudinal dataset of nearly 2 million tweets published over eleven years (2009–2019) by 67 political parties and their leaders in 10 western EU member states, to track whether European governance increase emphasis on EU affairs. I find that emphasis on European affairs increases at the time of European elections, referendum, European summits, major speeches of the European Commission president, and plenary sessions of the European Parliament. These results suggest that the exercise of supranational authority does indeed increase its visibility through the communications of political actors. Moreover, these findings have normative implications, as visibility is the first key requirement for the accountability of European governance.
