Voting is under way for today's runoff election, with all of Forsyth County's 33 precincts open until 7 tonight.

Republicans will weigh in on two local races.

Jim Boff and Julie Tressler are competing for the District 5 post on the county commission.

Though they qualify by district -- District 5 includes Cumming and much of eastern Forsyth County -- commissioners are elected countywide.

The two were the clear leaders in a July 15 field that also included two other candidates.

Incumbent Commissioner Linda Ledbetter chose not to seek re-election. There is no Democrat in the race, so Tuesday's winner will be the commissioner-elect.

Greg Allen and Charles Adams are battling to become the next clerk of court. The winner will succeed Doug Sorrells, who is retiring after 12 years at the helm.

Nearly 2,400 voters cast their ballots during last week's early voting period.

About 11 percent of the votes cast early have been Democratic ballots, which includes only the U.S. Senate race between DeKalb County CEO Vernon Jones and 18-year state legislator Jim Martin.

The winner will face Saxby Chambliss, the Republican incumbent, in the Nov. 4 general election.

Local election officials have said overall turnout for the runoff could be between 7 to 8 percent.
