Before revision: We study the voter model for opinion dynamics on a complete graph withstubborn nodes.
After revision: We address the phenomenon of sedimentation of opinions in networks and investigate how stubborn agents who never change their minds ("zealots") can influence the opinion of a social group. This is done via the voter model in which users are divided in two camps and repeatedly update their opinions based on others they connect with. Assuming zealots are present on both sides, the distribution of opinions reaches an equilibrium.
