The Return of the “Lurker”: A Longitudinal Study of Citizens’ Use of Social Media in Danish Elections 2011, 2015, and 2019

In this case study on Denmark, we particularly focus on trajectories of participation, the question of increasing mobilization, and the perceived outcomes in terms of efficacy. Contrary to other studies, we seek to establish a coherent perspective including the “silent majority.” By combining studies of participation, mobilization, and efficacy, we wish to provide not only a rigorous documentation of mobilization and efficacy of social media during election campaigns, but also a historic documentation of the participatory use and perception of social media as a democratic and political tool during three national election campaigns from 2011 to 2019.
