Based on 18 qualitative interviews, this article explores how the social media managers for the nine parties in the Danish parliament articulate the role of social media during the 2015 national elections. The article finds that the interviewees emphasise Facebook as an important means for one-way political communication and the monitoring of public opinion. The majority of the interviewees articulate a sense of responsibility for facilitating public debate on Facebook through the moderation of user-generated content and/or interactions with users. Yet the social media managers do not systematically analyse political input from social media users, nor do they see Facebook and Twitter as viable means of citizen influence on political decision-making. This is explained by a perceived lack of voter representativeness among Facebook users, fear of appearing politically imprudent and scepticism towards social media’s participatory potential.
