Sen. Kelly Loeffler (R) and Democrat Raphael Warnock are set to face off in a Jan. 5 runoff election after Rep. Doug Collins (R) conceded in Georgias special Senate election and the Associated Press projected they would receive the most votes.

Under the states rules, the contest goes to a runoff if no candidate wins a majority of the votes.

Loeffler has been in the Senate seat since December 2019, when Gov. Brian Kemp (R) appointed her after Republican Johnny Isakson retired. But the vacancy triggered a special election so that both of Georgias Senate seats were on the ballot this year.

The race was an open election, meaning that there were no primaries. Loeffler, Warnock and Collins consistently led the 20-person field, and a central question was whether any one candidate would be able to win a majority of votes to avoid triggering a runoff election.
