JoAnna Mendoza is the Democratic nominee for Arizona's 6th Congressional District, having won her July 2026 primary and now facing Republican incumbent Rep. Juan Ciscomani in a race widely rated among the most competitive in the country and one of the DCCC's top "Red to Blue" targets.

Raised in a farmworker family in rural Pinal County, Mendoza grew up relying on programs like food stamps and Section 8 housing. At 17, she enlisted in the U.S. Navy, later transferring to the U.S. Marine Corps, where she served as a Drill Instructor and deployed to both Iraq and Afghanistan over a 20-year military career. After retiring from the Marine Corps, she returned home to Arizona to raise her son, Aidan, as a single mother, earning a master's degree in leadership from Grand Canyon University in 2019.

Mendoza went on to serve her community as a governing board member for her rural school district in Red Rock, a veterans outreach coordinator for Pima Community College, a program manager at A Place Called Home, and a congressional staffer handling veterans' services for Rep. Tom O'Halleran in Arizona's 1st District. She has been endorsed by CHC BOLD PAC, the campaign arm of the Congressional Hispanic Caucus, and EMILYs List, among others.

  • JoAnna Mendoza has pledged to fight for:
  • Lowering costs and protecting families and seniors
  • Bringing good-paying jobs to Southern Arizona and protecting workers
  • Strengthening the healthcare system for families and veterans
  • Safe communities, strong borders, and real immigration solutions
  • Protecting Arizona's climate, water, and energy security for rural communities
  • Restoring trust and accountability in government
  • Keeping the country's promises to veterans
  • Strengthening national security and standing with U.S. allies
  • Mendoza has framed her candidacy around the discipline and mission-focus of her two decades in uniform, pledging to work with members of both parties to deliver practical results for Southern Arizona.
