In this essay, I have investigated the following questions: What is the Swedish Social Democratic Party's (Socialdemokraterna) view of volunteers in election campaigns? What does the party use volunteers for in election campaigns and with what purpose? I have conducted semi-structured interviews with representatives from five party districts which I have subsequently analyzed. The processing of my data has been done with the help of the the theory of communicative action's reasoning around publicity and legitimacy as well as the theory of rational choice and vote maximization. My findings point towards that to legitimize the party’s policy, interpersonal meetings are required, of which the meeting with the voter (door knocking) is the method that the party believes maximizes the benefit for that purpose and the implementation of which is based on volunteers.
