Loeffler, who was appointed late last year to fill the seat of retiring Sen. Johnny Isakson, faced multiple candidates in her race, including the Rev. Raphael Warnock, a Democrat, and GOP Rep. Doug Collins, depriving her of enough votes to win outright.
Loeffler and Warnock advanced to the runoff, CNN projected last week. CNN has not yet made a projection in the Perdue race, which featured three candidates. But Democratic candidate Jon Ossoff looks to be pulling Perdue below the 50% threshold, making it almost certain that the pair will also meet in the January 5 election, as both candidates are already campaigning for the runoff.
