Justice David Nahmias, 46, hopes to secure his position on Georgia's Supreme Court.
He was appointed to the bench last year by Governor Perdue, to fill retired Chief Justice Leah Ward Sears' seat.
Nahmias, who toured the Valdosta-Lowndes Regional Crime Lab Thursday, served nearly 20 years in public service as a federal prosecutor and Supreme Court law clerk.
"If you look at my record, you'll see I applied the law to the facts," said Nahmias. "I don't try to bend the law because I want it to go in a particular direction. And I'm fair and I'm impartial."
Nahmias faces family-law attorney Tamela Adkins in the runoff election.
It's set for Tuesday, November 30.
