Registered voters who come out to vote in next Tuesday’s general primary runoff may notice a slight change in the process, Clerk of Elections Erica Hamilton said.

When voters came to polling places in previous elections, a poll worker would type their name into a computer directory to verify their identity and generate each voter’s electronic ballot. The computer directory helps determine that people who come to vote are in fact registered to do so and for local elections, what voting precinct they live in.

Sometimes in the past, especially when printed voter rolls preceded computers, the process was slow, Hamilton said. Researchers at Kennesaw State University developed a device that can scan the barcode on voters’ driver’s licenses or photo IDs. The barcode links to the voter’s registration information, making the process quicker, Hamilton said.

Polling places will be open from 7 a.m. to 7 p.m. on Tuesday.

People who choose to vote in the runoff will be given a ballot for the same party whose ballot they selected in the general primary. Those who did not vote in the primary can still vote Tuesday; they will be able to choose either party’s ballot.

The Democratic ballot has just one runoff race, for Secretary of State, between Gail Buckner and Georganna Sinkfield.

The Republican ballot has four runoff races.

For governor, Republican voters can pick between Nathan Deal and Karen Handel; for attorney general, between Sam Olens and Preston W. Smith; for commissioner of insurance, between Ralph T. Hudgens and Maria Sheffield; and for public service commissioner, between John Douglas and Tim Echols.
