Ruben Gallego, a Democrat, has won the Arizona Senate seat, defeating Republican Kari Lake. Although the Democrats lost control of the Senate in the 2024 election, Gallego's victory helped to mitigate some of the losses. Republicans will have control of 53 seats for the next two years, having won Pennsylvania, Ohio, Montana, and West Virginia in the recent election. Gallego received $10 million in support from Fairshake, a crypto-focused super political action committee, and was predicted to win by both prediction markets and polling.
