A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. Arizona utilizes a semi-closed primary system. Unaffiliated voters may choose which party's primary they will vote in, but voters registered with a party can only vote in that party's primary.[1]

For information about which offices are nominated via primary election, see this article.

This page focuses on Arizona's 5th Congressional District Republican primary. For more in-depth information on the district's Democratic primary and the general election, see the following pages:

Key Messages

ELIMINATE FRAUD & CORRUPTION: We are tired of unaccountable power and political insiders. We follow the rules and fall behind while leaders rig the system and treat taxpayer dollars like Monopoly money. That ends now. I've been a fraud fighter for 25 years and I'll apply that experience to uphold the rule of law, root out fraud and abuse, and hold accountable anyone who breaks the rules. That includes leading legislation to eliminate corporate tax loopholes, end government subsidies for profitable companies, tackle insurance fraud and eliminate pharmacy benefit managers, enforce taxes on crypto profits, and ban dark money in politics. This is the DOGE we all deserved.

ACT NOW ON AFFORDABILITY: Everything costs way too much. We are tired of rich career politicians calling rising costs a hoax. They live in a different reality than us. This is a crisis and we feel it directly every single day. Rent, groceries, childcare, education, healthcare, energy, and insurance costs have skyrocketed the past 5 years. Young families can't afford to get started while seniors can't afford to slow down. I will spearhead legislation to boost housing supply, limit hedge fund investments in real estate, accelerate fusion and nuclear energy expansion, ensure low-cost community and tech college access, cap tariffs on international imports, and provide a public healthcare option that cuts costs and avoids insurers.

CUT SPENDING & FUEL AMERICA-FIRST INNOVATION: Taxpayers will pay almost $1 trillion this year to service our national debt - that's the entire defense budget. Congress has failed us and it holds hostage our kids' futures. We need a plan that reigns in spending while dramatically growing our economy through ingenuity and technology leadership at home and abroad. I will introduce legislation to launch the Innovation Corps, focused on developing scientific advances and technological breakthroughs that can be applied to challenges in AI, medicine, energy, transportation, infrastructure, housing, and healthcare. Purpose-driven, patriotic jobs that solve important problems in our communities - and create tech advances we can license globally.

Incumbent: No

Submitted Biography:  "Daniel Keenan is a dedicated businessman and lifelong resident of Arizona’s 5th Congressional District, deeply rooted in the communities of Gilbert and Queen Creek. Born and raised locally, Daniel graduated from Basha High School in 2005 and immediately entered the workforce. Growing up in a family built on hard work, his parents ran a small cleaning business before becoming successful home builders. Inspired by their example, Daniel learned the values of perseverance, accountability, and self-reliance at an early age. Without the benefit of a college degree, Daniel experienced firsthand the hardships faced by many blue-collar families, especially following the 2007 housing market crash. Determined to support his growing family, he took on multiple demanding jobs, including warehouse labor and agricultural work, often juggling long hours and double shifts to make ends meet. In 2014, driven by a strong entrepreneurial spirit, Daniel founded DK Builders, a residential construction company that has successfully built over 100 homes and created hundreds of jobs within the district. His experience overcoming economic challenges has reinforced his commitment to conservative principles of fiscal responsibility, limited government, and strong community values. Today, Daniel is running for Congress to bring these values and his real-world experience to Washington, DC. He is committed to protecting Arizona’s families, securing the border, defending the Second Amendment, and fighting"
