While the race didn't determine control of the Senate, it did increase Democrats' power in the chamber -- where Vice President Kamala Harris currently has to break ties -- rather than see the Republicans win a 50th seat and create procedural obstacles.
Walker, a businessman and local football legend, and Warnock, a noted reverend in Atlanta, first faced off in November's general election. But neither got 50% of the vote as required by state law, leading to Tuesday's runoff after about a week of early voting.
Polls closed at 7 p.m. ET in the Georgia Senate runoff race.
State officials said Tuesday they anticipate record turnout for a midterm runoff, with more than 1.4 million votes possibly cast on Election Day, on top of the nearly 1.9 million early votes.

After Georgia’s polls close at 7 p.m. ET, counties can begin reporting their vote totals, according to a Georgia secretary of state spokesperson. These numbers will most likely be early vote and absentees at first, which were able to start being tabulated at 7 a.m. on Tuesday
“Counties move through reporting Election Day totals as quickly as they can. Steady pace is typically the norm,” spokesperson Robert said.

A look back at Walker and Warnock's campaign messages
Warnock, in his second consecutive runoff election in less than two years, has campaigned heavily in recent weeks on the theme of “character.”A reverend at Martin Luther King Jr.'s former church and Georgia’s first Black senator, Warnock also pitched himself to the battleground state's voters as a pragmatic, experienced leader.
“I’ll put my character up against Raphael Warnock any day,” Warnock told ABC News on Tuesday.
While Walker has waved off or simply ignored the controversies surrounding his campaign, some of the issues raised by them have become a part of his messaging to voters on mental health, his Christian faith and his path to "redemption."
Walker has also tried to paint Warnock as a “rubber stamp” for President Joe Biden, describing himself as a potential check on the administration, which is unpopular in Georgia.
Warnock, in response to Walker’s characterization of him, said he's worked with Republicans during his nearly two years in Washington.
"I am the 18th most bipartisan senator in the Senate. Period,” Warnock told ABC News Congressional Correspondent Rachel Scott on Tuesday. “Now I know that’s an inconvenient fact for Mr. Walker. We also know that he’s allergic to facts, even the facts about his own life.”

Latest Election Day turnout prediction: More than 1.4M possible
The Georgia secretary of state’s office said late Tuesday afternoon that more than 1.4 million Election Day votes were possible by the time polls close at 7 p.m. ET in the runoff election.
“We’re projecting that that could very well be the pace if not higher,” secretary of state spokesperson Robert Sinners said, responding to an ABC News inquiry referencing reporting by The New York Times, which cited their office as saying as of 3:45 p.m. that officials expected between 120,000 and 140,000 votes to be cast per hour until the polls close and 1.014 million votes cast so far.
This exceeds earlier predictions by Gabriel Sterling, the chief operating officer for the secretary of state's office, who had said on Tuesday that between 1.1 million and 1.3 million people were likely to vote that day.
Sterling then said on CNN that the vote totals were getting close to the 1.35 million mark.
When it is all said and done, the secretary of state's office told ABC News that, with Election Day and early votes, "in total, it will be a record turnout for a midterm runoff."
