Georgia voters who consider themselves independents will have to pick a political party if they want to participate in primary elections for governorsecretary of state and state legislative races.

Voters won’t be able to take part in the state’s biggest races if they ask for a nonpartisan ballot for the May 22 primary election. Republican and Democratic primary contests only appear on partisan ballots.

Georgia has open primaries, which means voters can choose either party’s ballot without having to register with that party.

Voters should review sample ballots online or at voting locations before deciding which one they want to use, said Erica Hamilton, DeKalb County's elections director.

Many voters are accustomed to general elections in November, when all races appear on the same ballot, she said.

The only contested statewide race on nonpartisan ballots is for a judgeship on the Georgia Court of Appeals, where Ken Hodges faces Ken Shigley. Some areas have local nonpartisan races for judges, county commissioners and school board members.

Early voting for the primary election began April 30 and lasts until May 18.

The vast majority of voters have pulled partisan ballots so far, according to the Georgia Secretary of State's Office.

Through Wednesday, 46,660 people had voted on Republican Party ballots compared to 41,766 Democratic Party voters. Another 1,782 voters, or 2 percent of the total, used nonpartisan ballots.
