Both of the Senate runoff races in Georgia are neck to neck, a new poll found.

The two races could determine the majority party of the Senate — if both Republican incumbents were to lose, the Senate would effectively be tied 50-50, with Vice President-elect Kamala Harris (D) serving as the tiebreaker.

The Atlanta Journal-Constitution reported on the poll’s findings, which show Sen. Kelly Loeffler (R-Georgia) and Democratic challenger Raphael Warnock virtually tied 49-48, and Sen. David Perdue (R-Georgia) narrowly leading Democrat Jon Ossoff 50-46.

The results fell largely along party lines, though independent voters were evenly split in both races.

The poll, conducted by the Kansas-based Remington Research Group, was conducted Nov. 8-9, following the surprising results of the presidential election in which Georgia narrowly flipped blue — the first time the state has voted for a Democratic presidential candidate since 1992.

The survey also looked at the general favorability of each candidate, all with the exception of Warnock were roughly evenly split. Perdue’s was viewed favorably by 47% of the respondent and unfavorably by 45%, while Osoff’s favorability rating was 46% positive, 47% negative. Loeffler’s rating was along similar lines, at 46-44. Warnock’s was the highest at 49-38.

One of the reasons Warnock’s favorability rating is so much higher is because Loeffler had focused her attacks leading up to the Nov. 3 election on her Republican challenger Rep. Doug Collins (R-Georgia).

“Warnock didn’t take much heat in the general election because of the dynamics of that race,” said Titus Bond, the president of the group. “And it looks like Republicans are quickly falling behind Loeffler.”

The two runoffs will occur on Jan. 5 and have garnered national attention due to their potential to flip the Senate. Vice President Mike Pence visited Georgia on Monday, and many GOP leaders have called on the president to focus his support on the races.

The poll surveyed 1,450 likely voters and has a margin of error of +/-2.6%.
