ABSTRACT
When activists and organizations produce a political campaign, almost by definition they have to create complex communication infrastructures to attract the attention of the citizens. In this attempt, they can adopt a wide set of contrasting strategies of communication. For instance, activists can create a single, highly visible media source, or they can rely on a plethora of sympathetic blogs that communicate in an almost independent way. Moreover, the campaign organizers can open connections with political or media organizations active on other themes, or they can rely on a network of single-issue committees.
