2026 U.S. Senate election in Arizona
Arizona’s 2026 U.S. Senate race will decide a six-year seat in a closely divided swing state that often helps determine control of the chamber. The contest is expected to be shaped by the state’s partisan balance, with Democrats defending an incumbent seat and Republicans trying to capitalize on Arizona’s competitiveness. Key issues are likely to include the economy, immigration and border security, abortion, and national security. The race will also be defined by candidate contrast, including each side’s record on governing, messaging to independents, and alignment with national party leaders.
