STORY: At the Atlanta ballroom where Warnock's supporters gathered on election night, several hundred revelers erupted in applause when U.S. television networks called the race.
Many began dancing, some held their drinks in the air, and others took selfies to memorialize the moment. The group, a mix of young people, political activists, and wealthy professionals and donors, reflected the coalition of voters that Warnock drew on to win the contest.
The contest went to a runoff after neither candidate secured 50% of the vote on Nov. 8.
Warnock's victory was powered by a strong showing in urban and suburban counties, including Atlanta's Fulton County, where the incumbent Democrat was winning 77% of the vote - a higher share than he won in November.
Democrats now are on track for a 51-seat majority in the 100-seat Senate, which will make it slightly easier to advance Biden's nominees for judicial and administrative posts.
