In Arizona, Democrat Kyrsten Sinema has won the race for a U.S. Senate seat, defeating Republican and former U.S. Air Force pilot and colonel Martha McSally. She will replace outgoing Republican Senator Jeff Flake, who is retiring. Sinema, who worked on Ralph Nader’s presidential campaign in 2000, will become the first openly bisexual senator and the first female senator from Arizona. Her victory is the first time a Democrat has won a U.S. Senate seat in Arizona in 30 years, and means Democrats will have at least 47 seats in the Senate—as results from Florida and Mississippi remain uncalled.
