Janeese Lewis George received 52.9 percent of the vote in the District of Columbia's first ranked-choice Democratic mayoral primary, prompting Kenyan McDuffie to concede the race Thursday morning after securing 36.5 percent. With 73 percent of votes counted, all other candidates received less than 10 percent. The outcome occurred in a low-turnout contest where just over 60 percent of ballots had been tallied on election night.
