ABSTRACT The question of why political communication practitioners use social media for strategic political communication activities has rarely been investigated. By using well-established theoretical approaches of communication research, such as the influence of presumed influence approach, this study sought to determine the extent to which the subjective perceptions of German political communication practitioners explain their professional social media activities. The results of a survey (N = 1,067) indicate that the more political communication practitioners perceived that other political communication practitioners used and were influenced by Facebook and Twitter, the more often they used social media themselves. In contrast, the presumed reach of Facebook and Twitter among politicians, journalists, and citizens, as well as the presumed influence of both media on these groups, were not related to the practitioners’ social media activities. These findings suggest that the practitioners’ social media activities are driven more by an in-group orientation toward their colleagues and less by a strategic orientation toward external stakeholders.
