Georgia has clearly become less white in the last four years.

From The New York Times:

Georgia has clearly become less white in the last four years.

According to data from the Georgia secretary of state, the 2010 electorate was 66.3 percent white and 28.2 percent black. Since then, the white share of registered voters has fallen, to 58 percent from 62.6 percent. White voters turn out at somewhat higher rates than other voters in midterm elections, so we should expect the white share of the actual vote to be a little higher. Combining the data on registered voters with census data on the voter-eligible population, I expect the 2014 electorate to be about 64.2 percent white and 28.8 percent black. (Ms. Nunn is expected to win at least 90 percent of the black vote.)
