GOP organizations in nine of the 21 counties within the district endorsed Whitehead over Paul Broun of Athens, who came in second in the June 19 vote.
They were Richmond, Columbia, Lincoln, McDuffie, Putnam, Elbert, Stephens, Madison, and Towns.
This is more important than it sounds. With some exceptions, the nine counties generally run up the eastern-most side of the district, from Augusta north. On Tuesday, they produced 53 percent of the 54,229 votes counted to date.
