Rep. Kyrsten Sinema (D-AZ) won one of the tightest races in the country on Monday, breaking a decades-long Republican winning streak to become the first female U.S. senator from Arizona.

Sinema’s decision avoids a three-way contest, one of the most closely watched 2024 Senate races. Democrat Ruben Gallego and Republican Kari Lake are vying for the Arizona seat.

Sen. Kyrsten Sinema helped persuade leaders in both parties to limit many GOP amendments ahead of the debt-ceiling vote.

Sen. Kyrsten Sinema blamed partisanship for her departure, but her spending on luxuries, her defense of the filibuster and her protection of wealthy interests also doomed her chances for re-election.
