ATLANTA — Democrats were on the verge of taking control of the U.S. Senate early Wednesday morning after Raphael Warnock was declared the winner in his Georgia runoff election with GOP Sen. Kelly Loeffler, and Jon Ossoff pulled into the lead in his race with Republican Sen. David Perdue.

An African American pastor at Ebenezer Baptist Church — the Atlanta church made famous by the Rev. Martin Luther King Jr., — Warnock was declared the winner by the Associated Press with just over 97 percent of the votes counted. He delivered a victory speech shortly after 11:30 p.m. in a videotaped message delivered from his home in Atlanta.

“Georgia, I am honored by the faith you have shown in me. And I promise you this tonight, I am going to the Senate to work for all of Georgia,” Warnock said.

Minutes earlier, Loeffler, who was appointed to her Senate seat in 2019 by Georgia Gov. Brian Kemp, gave an impromptu speech but did not concede the race despite trailing Warnock by more than 35,000 votes with 97 percent counted.

“It’s going to be another late night,” she told a gathering of her supporters. “There are a lot of votes out there, as you all know. We have a path to victory, and we are going to stay on it.”

The campaign of Ossoff, a Jewish American activist and documentary film producer, also saw victory on the horizon early Wednesday, minutes before the vote count showed him surpassing Perdue.

When all the votes are counted we fully expect that Jon Ossoff will have won this election to represent Georgia in the United States Senate,” Ossoff’s campaign manager, Ellen Foster, said in a written statement. “The outstanding vote is squarely in parts of the state where Jon’s performance has been dominant. We look forward to seeing the process through in the coming hours and moving ahead so Jon can start fighting for all Georgians in the U.S. Senate.”

We look forward to seeing the process through in the coming hours and moving ahead so Jon can start fighting for all Georgians in the U.S. Senate.”

In a state where Joe Biden defeated President Trump by roughly 12,000 votes, both Senate contests were also close.

Should the Democrats pull off both runoff victories, they would earn a 50-seat tie with Republicans in the U.S. Senate, leaving Vice President-elect Kamala Harris to cast any deciding votes. Sen. Mitch McConnell, R-Ky., would also be denied a return to the role of Senate majority leader, which would fall to Sen. Chuck Schumer, D-N.Y.

A potentially seismic power shift, the Senate wins would mean that Republicans would not be able to block Biden’s Cabinet from being confirmed, nor would they be able to halt the Democrats’ ambitious agenda outright. Yet the final results of Ossoff’s race, as of early Wednesday, had yet to be determined.

That Democrats had managed to force two runoff elections, as well as Biden’s victory, had already come as something of a surprise in Georgia, a state that had reliably voted Republican for decades. With several third-party candidates in the race, none of the major-party Senate candidates cracked 50 percent in the Nov. 3 election, forcing runoffs. (Georgia is one of a handful of states that require an absolute majority in state elections.)

In pushing his claims of electoral fraud, Trump drove a wedge into the state’s Republican Party. He spent weeks angrily attacking Kemp and Georgia’s Republican secretary of state, Brad Raffensperger, accusing both of turning a blind eye to voting irregularities.

But Georgia held two separate recounts of the statewide results and conducted signature verifications of mail-in ballots in Cobb County that found “no fraudulent absentee ballots.” Those efforts did little to mollify Trump, who on Monday night railed against the vote tallies and promised to campaign a governor who he had once endorsed.

"I'll be here in about a year and a half campaigning against your governor, I guarantee you,” Trump said of Kemp.

The two Republicans in the race likewise offered voters a mixed message, agreeing with Trump that the November election had been “rigged” while urging supporters to the polls in the runoffs.

Loeffler announced Monday that she would object to the certification of the Electoral College vote in Congress on Wednesday. Perdue said he also supported that effort, but while quarantining would not be in the chamber to offer his objection.

In many ways, the two races were run in tandem, with the Republican candidates accusing the Democrats of being “radicals” and “socialists,” while Warnock and Ossoff countered that Loeffler and Perdue were the “Bonnie and Clyde of corruption.” Both were accused of making profitable stock trades at the start of the pandemic, after receiving classified briefings at a time when most Americans had little idea of the impending devastation. Neither has been charged with a crime.
