Democrats gain control of Senate as Warnock and Ossoff projected to win in Georgia

In a monumental power shift, the control of the U.S. Senate is now projected to be in the hands of Democrats for the first time in a decade after the Rev. Raphael Warnock and Jon Ossoff are projected to defeat Republican incumbents Kelly Loeffler David Perdue in twin runoff elections in Georgia.

After coming up short in several key Senate races in November, Warnock and Ossoff’s wins mean both Republicans and Democrats hold 50 seats in the Senate, with Vice President-elect Kamala Harris in a position to cast tie-breaking votes.

It’s also a massive boost to the incoming Biden administration looking to quickly roll out its agenda. With two weeks until his inauguration, President-elect Joe Biden now knows he will have the power to maneuver on policy and nominations with Ossoff and Warnock in Congress.

"You will make a decision about who is holding these most powerful positions that will chart the course of Georgian families and families all around our country. So I’m here to thank you, on behalf of Joe and myself, for what you did in November. And I'm here to ask you to do it again," Harris said on Sunday in Savannah, Georgia. "Everything is at stake."

Ossoff and Warnock aimed to repeat Biden's November victory -- when he became the first Democrat to win Georgia since 1992 -- by relying on the state's shifting demographics and the influence of minority voters, particularly Black voters.

Both Democrats and Republicans campaigned in tandem. But the stakes were higher for Ossoff and Warnock: Had just one failed to knock off either Perdue or Loeffler, who campaigned in lockstep with President Donald Trump, the GOP would have retained control of the Senate for at least the next two years.

While Democrats have performed well in early voting, both sides watched election day turnout in the state’s conservative congressional districts.

And as Trump faces criticism for his attempts to pressure Georgia’s Republican secretary of state to "find" votes to overturn Biden’s victory, officials in both parties in Georgia and Washington are bracing for another lengthy and acrimonious vote-counting process.

In a sign of the importance of the dual Senate races, Biden, Harris, Trump and Vice President Mike Pence have traveled to Georgia in the days leading up to the election to rally supporters and activate their respective bases.

"It's a biggie. Our country is depending on you. The whole world is watching the people of Georgia," Trump said of the contests as he stumped for Loeffler and Perdue on the eve of the runoffs in Dalton, which sits in the northwest portion of the state near the border of Tennessee.

"Georgia, the whole nation is looking to you to lead us forward," Biden said at a drive-in rally on Monday, during his second trip to Atlanta to campaign alongside Warnock and Ossoff. "The power is literally in your hands unlike any time in my career -- one state. One state can chart the course, not just for the next four years, but for the next generation."

History remains on the GOP's side since runoffs in the state have historically favored Republicans. Even more than a quarter century ago, when former President Bill Clinton captured Georgia's electoral votes, Democratic Sen. Wyche Fowler led in the general election but ultimately lost to Republican Paul Coverdell in the overtime rematch.

"Republicans are going to make sure that they show up," said Jay Williams, a Republican consultant in Georgia. "They're not going to cut off their noses to spite their face."

But some Democrats in the state believe Trump’s extraordinary attempts to subvert the democratic process are deterring the GOP's base from showing up for a second time.

"There’s a schism in the Republican Party that has to be dispiriting to Republicans, for those who have not voted yet, I’m sure these current events, like the president’s newly released taped phone call, will have some bearing on their vote (Tuesday)," said Rep. Hank Johnson, who represents the suburbs east of Atlanta.

Johnson added that for Democrats to succeed on Tuesday, robust turnout is central to their effort to match Biden's victory.

"Democrats are looking at the fact that we have the nation’s future in our hands. All we have to do is turn out," he continued. "Georgia Democrats are looking at this election not just for the salvation of the state of Georgia, but what it means for the country."
