Georgia voters are heading back to the polls for the final time this year to settle three statewide races that remain undecided following the Nov. 4 election.

The race for U.S. senator between Republican incumbent Saxby Chambliss and Democratic challenger Jim Martin heads the ballot. Also to be settled are state contests for Public Service Commission and Appeals Court judge.

Runoff voting day is Tuesday, with polls open from 7 a.m. to 7 p.m.

All standard voting procedures remain in place for the runoff.

Only registered voters are eligible, but even those who did not vote on Nov. 4 may cast a ballot. Voters will need to produce a valid photo ID to cast a ballot.
