Southern Arizona has a new voice heading to Washington, and the shift is altering the lineup in the House of Representatives. Democratic candidate JoAnna Mendoza has won a competitive race for Arizona’s 6th Congressional District, flipping the seat and denying Republican incumbent U.S. Rep. Juan Ciscomani a third term, azfamily.com reported.
A Tight Race Decided by Thousands of Votes
The Associated Press called the race early Thursday afternoon, projecting Mendoza to victory with about 53% of the vote. Ciscomani pulled in nearly 45%, leaving Mendoza with a lead of roughly 25,000 votes, according to election officials cited by kvoa.com. This contest marks the first time Mendoza has ever been elected to public office.
Her path to Capitol Hill breaks new ground. Born in Pinal County as the daughter of farmworkers, Mendoza served two decades in the U.S. military—including deployments to Iraq and Afghanistan—and worked as a drill instructor. Progressive group VoteVets notes that she is the first female Marine elected to Congress, bringing a distinctly different background to the legislative branch.
Mendoza Targets Ciscomani over Legislative Record and SNAP Cuts
Throughout the campaign, Mendoza zeroed in on Ciscomani’s legislative record, particularly criticizing his vote for President Donald Trump’s signature legislation, known as the “One Big Beautiful Bill.” That law enforced stricter work requirements for SNAP benefits, resulting in millions of people losing access, with Arizona among the hardest-hit states.
Ciscomani first won the seat in 2022, a victory that helped Republicans reclaim control of the House at the time, and he narrowly won a second term in 2024. While he attempted to distance himself from Trump during this cycle, voters expressed deep frustration over the broader economy, climbing living costs, healthcare expenses, and U.S. involvement in the Iran war, which sent gas prices soaring.

Nationwide, the discontent translated into widespread losses for Republicans, who lost control of both chambers of Congress in Tuesday’s midterms. A surge of young, Black, and Hispanic voters helped propel Democrats to historic wins across the country, making Arizona’s 6th District one of dozens of seats to flip sides.
Looking Ahead to the 120th Congress
Following the race call, Ciscomani released a statement reflecting on his tenure.
“Serving the people of Arizona’s 6th Congressional District for the last four years has been the honor of my lifetime,” Ciscomani said. “I came to Congress with a commitment to serve, put people over politics, and get things done. That commitment has never wavered and it never will. From the bottom of my heart, thank you!”
For her part, Mendoza acknowledged the heavy skepticism facing incoming lawmakers, noting that public dissatisfaction extends across party lines.
“People are not happy with government period and that includes Democrats as well we need to be clear eyed that we’ve got a lot to prove,” Mendoza said to News 4 Tucson. “We have to take action we cannot sit on our hands and think oh well everyone loved us cause they voted for us.”
Mendoza has outlined tariffs, the war with Iran, and the high cost of living for Southern Arizona families as her primary focuses once in office, adding that she hopes to work with President Donald Trump to achieve those goals. She is scheduled to be sworn into the 120th Congress on Sunday, January 3, 2027.
