Networks in electoral behavior, as a part of political science, refers to the relevance of networks in forming citizens’ voting behavior at parliamentary, presidential or local elections.  There are several theories emphasizing different factors which may shape citizens' voting behavior.  Many influential theories ignore the possible influence of individuals' networks in forming vote choices and focus mainly on the effects of own political attitudes – such as party loyalties or party identification developed in childhood proposed by the Michigan model, or on the influence of rational calculations about the political parties’ ideological positions as proposed by spatial and valence theories.  These theories offer models of electoral behavior in which individuals are not analyzed within their social networks and environments.  In a more general context, some authors warn that the hypothesis testing done mainly based on sample surveys and focused on individuals’ attributes without looking at relational data (relations among individuals) seems to be a poor methodological instrument.  However, models emphasizing the influence of individuals’ social networks in shaping their electoral choices have been also present in the literature from the very beginning.
