The Atlanta mayor’s race won’t be the only thing on the Nov. 30 runoff ballot. A half-dozen council seats and the City Council president post will be determined through one-on-one contests. Atlanta also has runoff elections for School Board.

Elsewhere in metro Atlanta, there are a number of cities with runoff elections, including four cities with mayoral runoff elections.

Runoff elections are required in Georgia for races in which no candidate received more than 50% of the vote in the general election on Nov. 2.

To find out if your voting precinct has a runoff election and to see sample ballots, visit your county elections office website or the Georgia My Voter Page.

Why Georgia holds runoff elections: If you think it’s unusual to have a runoff election in November, it is. As many as 10 states require runoffs for primary elections, but Georgia is believed to be the only state that requires a runoff in any general election contest in which no candidate wins 50 percent of the vote. Georgia’s runoff law made national news in January, when runoff elections for both of Georgia’s U.S. Senate seats gave Democrats a majority in the Senate.
