Democrat Ruben Gallego has been projected to win Arizona's U.S. Senate seat against Republican Kari Lake, marking her second consecutive electoral defeat. Gallego, who has served in the U.S. House since 2015, will succeed Kyrsten Sinema, who chose not to seek reelection after switching to Independent. In a close race, newly counted ballots from Maricopa County favored Gallego, pushing his lead over Lake to over 12,000 votes. This victory for Gallego is a small yet significant win for Democrats amid a challenging election cycle, though the overall control of Congress remains uncertain. Lake, a former news anchor and staunch Trump supporter, faced backlash over her past election denial claims, which influenced her campaign. With Gallego's win, Democrats maintain both Senate seats in Arizona, previously held by Sinema and Mark Kelly.
