Do Voters Respond to Cross-Ethnic Campaigning inDivided Societies?
In order to comply with electoral rules incentivizing cross-ethnic mobilization, candidates in divided societies often campaign in opponents’ strongholds among non-coethnics. In this paper, we show that such cross-ethnic campaign rallies may actually depress outgroup candidates’ support among non-coethnics. We argue that candidates’ holding of campaign rallies in non-coethnic constituencies can inadvertently trigger perceptions of intergroup competition, increase the salience of ethnicity, and depress support for non-coethnic candidates. We leverage a natural experiment that exploits the timing of an unscheduled campaign rally held by a presidential candidate in a non-coethnic county in his opponent’s stronghold during Kenya’s 2017 election. In comparing survey respondents before and after the rally, we find that the candidate’s post-rally favorability significantly decreased among non-coethnic voters, while the proportion of voters identifying in ethnic terms simultaneously increased. These findings have important implications for the efficacy of institutional design to promote cross-ethnic political mobilization in polarized societies.
