In democratic Africa, where ethnicity is a key driver of vote choice, politicians must attract voters across ethnic lines. This article explores one way politicians can do this: by appealing to a coethnic bond through their spouse. We propose that cross-ethnic spouses can help candidates send credible signals of coalition building before an election. We test this argument with a survey experiment in Benin, where President Yayi has married across ethnic lines. Our results confirm that priming the first lady’s ethnicity increases support for President Yayi among her coethnics. We generalize these results by combining new data on leader-spouse ethnicity with Afrobarometer survey data. Our results suggest that cross-ethnic marriages are one tool leaders can use to shore up support in multiethnic elections.
