Tuesday’s special election in Arizona’s 7th Congressional District seems poised to further tighten the Republican majority in the U.S. House. In this area, which stretches from Yuma to Tucson along the Mexican border, Democrats have a significant 2-to-1 advantage in voter registration.
Democrat Adelita Grijalva, currently a Pima County Supervisor, is running against Daniel Butierrez, a Republican and the daughter of a late Congressman. Butierrez, who’s also a small business owner, presents herself as a candidate for change in a district that has been Democratic for over two decades.
Grijalva has publicly criticized what she describes as President Trump’s harsh policies, particularly pointing to the negative impact they’ve had on thousands of Arizonans. In a social media post, she expressed determination to fight against what she sees as detrimental legislative measures.
On the other hand, Butierrez has been vocal about the need for representation that truly embodies the entire community, suggesting that voting is essential to fend off extremist views. She’s told constituents that this election is an opportunity to select a representative who can unite rather than divide.
The winner will fill the remaining 15 months of Grijalva’s late father’s term, who passed away in March due to complications following cancer treatment. As it stands, Republicans control the House with a slim margin of 219 to 213, and three seats are currently vacant.
There are also other special elections set to fill vacant seats, such as in Texas’ 18th District, where there will be an election on November 4, 2025. This was prompted by the death of a Democratic representative. Similarly, Tennessee’s 7th District is also preparing for its special election in December after the Republican representative resigned.
Grijalva’s candidacy has gained significant traction, bolstered by support from prominent progressives, earning her more than 60% of primary votes this summer among a crowded field. If elected, she would make history as Arizona’s first Latina representative in Congress.
Butierrez, who previously lost in the GOP primary, is hoping to leverage a renewed Republican push in the district. The dynamics have shifted somewhat since Trump narrowly lost Arizona in 2020; the Democrats took the district decisively in 2024, showing a potential trend that could influence future races.
