We analyze a model of political campaigns, where a challenger aims to unseat an incumbent. The challenger and the incumbent differ in their quality. All voters want to elect the candidate with higher quality. The challenger chooses the level of precision of campaign messages to affect his probability of being elected. More precise campaigns are more costly for the challenger. We characterize the equilibria when voters observe both the message and the precision. We show that only two-step non-trivial equili- bira are possible. This framework allows us to investigate welfare effects of campaign spending rules.
