Forsyth County's elections supervisor said her prediction of 5 percent voter turnout in Tuesday's runoff election for the 9th District U.S. House seat was more than doubled.

“I’m going to start thinking bigger here in this county,” Barbara Luth said after about 10.7 percent of the county's eligible registered voters cast ballots.

“It was a real good turnout and our poll workers did a wonderful job. Everything went smoothly last night,” she said.

In what has been a busy, if not confusing, election cycle, Luth said early voting in the July 20 primary began Monday and runs through Juy 16.

Early balloting will be expanded to four satellite precincts the week before the election.

The primary ballot features contested races for local office, including county commission and school board, and statewide posts, including governor.

“I think especially in the areas where we have the commissioners and the school board members from the county running, I think those areas will really come out and vote and then again we have the congressional seat back into that,” Luth said.

Tuesday's election filled the unexpired 9th District U.S. House term of Nathan Deal, who stepped down to run for governor.

A full, two-year congressional term is at stake in July.

“If all the people who voted for just the congressional come out and more, we’ll be in good shape," Luth said.
