There are plenty of races on the ballot for Gwinnett County voters in this month's runoff elections.

The options for advance voting, though, are more limited than during the general primary.

A new commission is considering the next generation of voting machines met for the first time.

Advance voting for runoff races — which range in Gwinnett from a local judicial seat to a Republican gubernatorial primary and a Democratic Congressional primary — began Monday and continues through July 20, the Friday before the July 24 election day. Those eligible to vote can cast in-person ballots between 7 a.m. and 7 p.m. Monday through Friday at the Gwinnett elections office.

That office is located at 455 Grayson Highway in Lawrenceville. No other locations are open for early voting and there will be no Saturday voting.

The elections office will be closed closed on July 4.

Voters must vote in the same party they chose for the general primary. Those who did not vote in the primary or voted nonpartisan can choose whichever party they like.

Voters can also request an absentee ballot until July 20. Those who wish to do so can call 678-226-7210 or complete the form online.

In addition to the Republican gubernatorial primary between Casey Cagle and Brian Kemp, some Gwinnett voters will be able tot vote in the Democratic runoff for U.S. House District 7.

Carolyn Bourdeaux and David Kim are vying for the right to challenge Republican incumbent Rob Woodall in November.

Three Republican primaries for Gwinnett-based state legislature seats are headed for runoffs as well:

  • In Duluth-based District 97, attorney Bonnie Rich took the most votes in a six-candidate race to replace longtime legislator Brooks Coleman — but she couldn't eclipse the 50 percent mark. Kipper Tabb was the second-highest vote getter and will compete with Rich for the right to take on Democrat Aisha Yaqoob in November's general election.
  • In Lawrenceville-based District 102, which was vacated by Buzz Brockway for what turned out to be an unsuccessful run at Secretary of State, former Gwinnett planning commissioner Paula Hastings took the most votes in a three-person Republican race. Zach Procter eked out a second-place finish. The runoff winner will face Democrat Gregg Kennard in November.
  • In Grayson-based District 105, where incumbent Republican Joyce Chandler opted not to run again, former State Rep. Donna Sheldon and Robin Mauck, the director of a nonprofit medical clinic, dominated a three-candidate contest. The winner of July's runoff will face repeat Democratic candidate Donna McLeod for what's become one of the most competitive — and controversial — districts in Georgia.

There is also a spot on Gwinnett County’s Superior Court bench up for grabs, with Veronica Cope and Tracey Mason having survived the original five-candidate primary.
