Political activism in the age of social networks:

the point of view of social macroscopes



Abstract: A candidate has at least three levers to win public votes: convince of the relevance of their political agenda and their ideas (positive campaigning), convince of the inadequacy or the danger of the programs and ideas of their adversaries (negative campaigning), and make their name and that of their party sound familiar. Taking the example of the French presidential election (2017), we study how politicians use social medias to operate these levers and how these actions are articulated with those of their Twitter communities of activists. We propose a set of quantitative measurements at different scales to characterize the processes operating within the political communities, and we show that these communities have distinct ways of articulating with their leader’s strategies, pointing to a heterogeneity in the forms of “division of militant labor”. We also show that variations in the community strategies allow to identify temporary weaknesses or a loss of trust in a leader, as well as the structural position of the candidates within the political arena. Moreover, we identify an anomaly in the attitude of all the candidates towards Marine Le Pen.
