Democrat the Rev. Raphael Warnock holds a lead over GOP Sen. Kelly Loeffler (Ga.) in a poll of one of two Georgia runoff races that will determine the balance of the Senate.

Warnock leads Loeffler 52 percent to 45 percent in a new poll from SurveyUSA commissioned by WXIA-TV in Atlanta.

The poll, released Thursday, also shows that Democrat John Ossoff is narrowly leading Sen. David Perdue (R-Ga.) 50 percent to the Republican’s 48 percent in the state’s other runoff election that will take place in January. 

White voters in the Peach State gave Perdue a 43-point lead and Loeffler a 37-point lead, according to the poll. Among Black voters, Ossoff led in his runoff race with an 87-point advantage and Warnock with an 83-point advantage.  

Men gave Perdue a 10-point lead over Ossoff and Loeffler a 9-point lead over Warnock. Women gave Ossoff an 11-point lead over Perdue, as well as a 19-point advantage for Warnock.

Georgia voters will head to the polls in the runoff election on Jan. 5. If either Republican wins, the GOP will retain control of the Senate. However, if both Democratic candidates win, the parties will be evenly split in the upper chamber, allowing Vice President-elect Kamala Harris to cast a tie-breaking vote on legislation.

The Thursday poll used online interviews with 850 Georgia adults between Nov. 27 and Nov. 30. 717 are registered to vote and 583 were determined to be likely to vote in the January runoff.
