LAWRENCEVILLE -- One in four of Gwinnett's nearly 400,000 registered voters cast ballots in Tuesday's primary elections.
The number eclipsed recent primaries, including 2008's 15 percent and 2010's 21 percent.
But that number is likely to dwindle when three local elections are decided in the Aug. 21 runoff.
During Tuesday's voting, District 3 Commissioner Mike Beaudreau came close to a majority in the GOP primary. But with 47 percent, he is now set to square off against Tommy Hunter, the second-place finisher, in the runoff.
That race will be on ballots alongside two countywide judicial races.
In a Superior Court race to replace Dawson Jackson, the top two finishers -- Kathy Schrader and Tracey Mason Blasi -- will face off in a month.
For a State Court seat, the runoff comes down to attorneys Emily Brantley and Pam Britt.
Gwinnett Elections Director Lynn Ledford said the runoff turnout will be hard to predict, but it usually goes down from the primary. In 2008, 9.8 percent of people voted and in 2010 it was 21.3 percent.
Ledford noted than anyone who voted in either party or who did not vote Tuesday may participate in the judicial runoffs. For Distrit 3 residents, the runoff will be open to GOP voters and people who did not vote in the primary.
