Title: Echo Chambers: voter-to-voter communication and political competition

Abstract. The rise of social media technologies has greatly increased the amount of voter-to-voter communication that is present in modern political systems. I investigate, in a model of informative campaign advertising, how the ability of voters to strategically communicate with each other shapes the advertising strategies of two competing parties. My primary interest is the effect of strategic communication in the voter network on information diffusion and aggregation. Two main results are put forward. First, information does not travel among voters biased toward different parties even if they are ideologically close - ”echo chambers” arise endogenously. Second, whenever like-minded voters do not communicate with each other often enough (low homophily), parties tailor their advertising on the opponent’s supporters rather than on swing or core states voters.
