Black voters have historically supported the creation of charter schools in Georgia, but they were a major force in the election day defeat of the referendum that could have turned low-scoring schools in their neighborhoods into the independently run schools.

Majority black metro Atlanta precincts voted overwhelmingly in 2012 to let the state, and not just school districts, create charter schools. But nearly 70 percent of them voted against this year’s constitutional amendment that would have created a statewide school district to take over “chronically failing” schools. That compares with 55 percent of “no” votes in majority white precincts.
