Black and Latino voters support coethnic candidates at high rates in local elections. What is less clear is how Black and Latino voters respond to out-group candidates when they do not have the option to support a coethnic candidate. I posit that when race and ethnicity become salient in a campaign, endorsements from Black and Latino leaders and organizations increase support of out-group candidates among Blacks and Latinos. I find that this hypothesis is strongly supported among Blacks. However, the same is not true for Latinos, most likely because of the political heterogeneity of the group. Using data from a survey experiment, I show that Black endorsements of minority out-group candidates are persuasive for Blacks, while comparable endorsements from Latinos are not as influential among Latinos.
