In Ferguson-Florissant, Mo. school board elections, voters get one vote for every school board seat—but a voter can’t use, say, three eligible votes on the same candidate. From 2000 through 2015, white candidates win 59.5 percent of the time, while black candidates win just 20.8 percent of the time—even though whites and blacks make up roughly equal shares of the voting-age population (per the 2010 census). District court: There’s no allegation of intentional discrimination, but the electoral process does afford black voters fewer opportunities to elect their preferred candidates. District court again: To remedy that, “plumping” will be allowed: Voters can vote more than once for the same candidate. So, if there are three seats up for grabs, voters can vote up to three times for their preferred candidate. Eighth Circuit: Affirmed.
