# Ruben Gallego Democratic US Senator from Arizona, elected in 2024 after defeating Republican Kari Lake — a Trump-endorsed election denier — in one of the cycle's most-watched races. A Marine combat veteran who served in Iraq, Gallego previously represented Arizona's 3rd (later 7th) Congressional District from 2015 to 2025. His Senate victory was notable for outperforming the top of the Democratic ticket in Arizona, demonstrating that a Latino veteran who ran on kitchen-table issues could win in a swing state even as Democrats lost nationally. Gallego appears in the vault in discussions of policy front-running and market manipulation around the Iran tensions — part of the broader pattern of tracking how political actors intersect with defense and foreign policy decisions that move markets. ## See Also - [[Donald Trump]] — whose endorsee he defeated in 2024
