Incumbent Rep. Adelita Grijalva (D), who won a decisive special election victory in September 2025 following her father Raúl Grijalva's death, recently filed for re-election ahead of Arizona's April 6 deadline, solidifying her position in the solidly Democratic AZ-07 district rated D+13 on the Cook Partisan Voting Index. Trader consensus reflects the district's consistent Democratic dominance in recent cycles, strong Hispanic voter turnout, and historical incumbent re-election rates exceeding 90% in safe seats. With primaries set for July 21, 2026, odds could shift via a contested Democratic primary producing a weaker nominee, a high-profile GOP challenger emerging, major scandal or legal issues targeting Grijalva, or a national Republican midterm wave, though such upsets remain rare in D+13 territory.
