Republicans have expanded their voter registration advantage over Democrats in Arizona to 333,255 registered voters, according to the latest October 2025 report released by the Arizona Secretary of State’s Office.
The newest data shows Republicans now total 1,603,141 registered voters (35.63%), compared to 1,269,886 Democrats (28.23%). Another 1,625,968 voters are registered as “Other,” which includes independents and minor parties such as Libertarians (32,026), No Labels (42,277), and Greens (5,212). Arizona’s overall active voter registration stands at 4,498,995.
Since July, Republicans have added 5,436 new voters, while Democrats lost 421, according to changes noted in the official quarterly report. Historical data compiled by the Secretary of State’s office shows this partisan gap widening steadily in recent years. Republicans led by 295,000 voters in 2024, 166,000 in 2022, and 130,000 in 2020. As of October 2025, that lead now surpasses 333,000 — the largest margin in nearly a decade.
County-level data reveals that Maricopa County, Arizona’s largest, remains a focal point of both parties’ registration efforts. The October report lists 940,727 registered Republicans, compared to 744,804 Democrats, giving the GOP a nearly 196,000-voter advantage in the county. In traditionally conservative counties like Yavapai, Mohave, and Pinal, Republicans maintain commanding leads, while Pima County continues to serve as the Democratic stronghold with 247,221 Democrats to 191,977 Republicans.
The data also shows continued growth in unaffiliated voters, reflecting Arizona’s independent streak. The “Other” category now represents more than one-third of all registered voters (34.37%), and its steady rise across counties — particularly in Maricopa, Pima, and Yuma — highlights how nonpartisan voters could decide close statewide races.
The voter registration update comes less than a year before the 2026 gubernatorial election, in which Republicans aim to unseat Governor Katie Hobbs (D). Political analysts note that while registration advantages can shape turnout dynamics, Arizona’s large share of unaffiliated voters keeps the state in competitive territory.
The report also tracks 409,091 inactive voters, those whose registration may need updating due to address or status changes. Among inactive registrations, Republicans slightly outnumber Democrats — 110,196 to 106,623 — though both parties show similar proportional shares. The next update from the Arizona Secretary of State is expected in early 2026. With voter registration surpassing 4.49 million and growing each quarter, Arizona remains one of the most closely watched swing states in the nation heading into the 2026 election season.
