Arizona voters are poised to head to the polls on Tuesday, July 22, 2026, to determine the Republican contenders who will challenge Democratic Governor Katie Hobbs, alongside critical primary races in several congressional districts that could significantly influence the ongoing battle for control of the U.S. House of Representatives. These primaries arrive at a pivotal moment for Arizona, a state that has transitioned from a traditionally Republican stronghold to a fiercely contested battleground, reflecting broader national political currents and deeply entrenched debates over election integrity.
Arizona’s Evolving Political Landscape: A Swing State in the Spotlight
For decades, Arizona was reliably red, a bastion of conservative politics, epitomized by figures like Barry Goldwater and John McCain. However, the 21st century has witnessed a dramatic demographic and political transformation, shifting the state’s electoral map towards a purple hue. This evolution is driven by several factors: a burgeoning Hispanic population, which tends to lean Democratic; an influx of new residents from other states, many bringing diverse political affiliations; and a growing urban-suburban divide that increasingly favors Democratic candidates in metropolitan areas like Phoenix and Tucson.
The shift is evident in recent election outcomes. While six of its nine House representatives are currently Republicans, the state now boasts a Democratic governor, Katie Hobbs, and both U.S. Senators, Kyrsten Sinema (Independent, formerly Democrat) and Mark Kelly, are Democrats. The presidential election results further underscore this volatility: Arizona narrowly voted for former President Joe Biden in 2020, marking a significant Democratic victory in a traditionally Republican state, only to flip back in 2024, delivering its electoral votes to former President Donald Trump. This swing state status ensures that every election cycle in Arizona, particularly the primaries, draws intense national scrutiny and investment.
The Lingering Shadow of Election Integrity Claims
Following the 2020 presidential election, Arizona became a focal point for former President Trump’s unsubstantiated claims of widespread voter fraud. These allegations, amplified by certain political figures and media outlets, have continued to reverberate throughout the state’s political discourse, shaping voter confidence and becoming a litmus test for many Republican candidates. The issue isn’t merely a fringe concern; a 2024 study by Arizona State University’s Center for Latina/os and American Politics Research (CLAPR) revealed that one in three Arizona voters expressed being "not that confident" or "not at all confident" that absentee or mail-in ballots would be fairly counted and free of fraud.
Francisco Pedraza, head of CLAPR, highlighted the profound impact of these sustained claims, noting that "when thought leaders — and especially elected officials, public officials, including the president of the United States — when they continue to bang on this drum that there’s fraud happening despite no evidence that that is the case, it sticks, and so people’s beliefs are really tainted." This sentiment underscores how central the "election integrity" narrative remains, particularly within the Republican primary electorate, influencing candidate platforms and voter behavior.
The Gubernatorial Showdown: Hobbs Awaits GOP Challenger
On the Democratic side, Governor Katie Hobbs is running unopposed for her party’s nomination, setting the stage for a general election battle against one of four Republican candidates. Hobbs, who narrowly defeated Trump ally Kari Lake in the 2022 gubernatorial race by just over 17,000 votes (0.67%), has focused her tenure and re-election campaign on kitchen-table issues such as affordability, economic development, and curbing school vouchers, a move that resonates with a broader electorate. Her 2022 victory, achieved despite a challenging national environment for Democrats, demonstrated her ability to navigate a highly polarized political landscape.
The Republican primary for governor features a competitive field, with U.S. Representatives Andy Biggs and David Schweikert emerging as the leading contenders. Early polls suggest Biggs holds a lead, and his campaign has been significantly bolstered by a coveted endorsement from former President Trump. Pedraza anticipates a "tight race" should Biggs secure the nomination against Hobbs, given the state’s recent electoral history.
Andy Biggs: A Conservative Firebrand and Trump Loyalist
Congressman Andy Biggs, who has represented Arizona’s 5th District for five terms, is a prominent figure within the conservative movement, having formerly chaired the influential House Freedom Caucus. Biggs has been one of the most vocal proponents of former President Trump’s election fraud claims. His involvement in the events surrounding January 6, 2021, and his efforts to persuade state officials to overturn the 2020 election results, led to a subpoena from the now-defunct Jan. 6 select committee. His name appeared frequently in the committee’s final report, detailing his alleged role in plans to bring protesters to Washington and his communications with state officials regarding the election.
Biggs’ platform centers on fiscal conservatism, border security, and what he terms "election integrity." His strong ties to the Trump wing of the Republican Party and his unwavering commitment to conservative principles make him a formidable candidate in the primary. His campaign messaging is expected to heavily lean into national issues, criticizing Hobbs’ policies and aligning closely with the national Republican agenda.
David Schweikert: From Congressional Gridlock to Gubernatorial Ambition
Congressman David Schweikert, first elected to Congress in 2010 as part of the Tea Party wave, currently represents a district encompassing parts of Scottsdale. Schweikert’s decision to run for governor stems from his expressed frustration with congressional gridlock, as he told the Arizona Republic last year: "We have a body that can’t even pass its appropriation bills." His campaign is expected to focus on state-level issues and his experience as a seasoned legislator, potentially offering a more pragmatic alternative to Biggs’ firebrand style.
Schweikert’s most recent congressional victory in 2024 was by a relatively narrow margin of 3.8 points against former state legislator Amish Shah, indicating his district’s increasing competitiveness. While his congressional record reflects conservative principles, his emphasis on governance and legislative effectiveness may appeal to a segment of the Republican electorate seeking a different approach.
The primary outcome will hinge on which candidate can best mobilize the conservative base, with Trump’s endorsement likely to be a significant factor in Biggs’ favor. The winner will face the challenge of unifying the Republican party behind a single candidate while simultaneously attempting to appeal to the broader Arizona electorate in the general election against Governor Hobbs.
Arizona’s 1st Congressional District: A National Battleground
With David Schweikert vacating his seat to run for governor, Arizona’s 1st Congressional District (AZ-01) has become one of the most closely watched races nationally. Ranked as a "toss-up" by Sabato’s Crystal Ball rankings from the UVA Center for Politics, this district is crucial for both parties in their quest for House control.
On the Republican side, a crowded field includes former state Rep. Joseph Chaplik, former Arizona Cardinals kicker Jay Feely, and businessman John Trobough. Former President Trump has thrown his weight behind Feely, whose name recognition and Trump’s endorsement could give him a significant edge in the primary. Feely’s campaign is likely to focus on conservative principles and strong support for the former president’s agenda. Chaplik, with his legislative experience, and Trobough, potentially self-funding, will aim to carve out their own paths.
The Democratic primary is equally competitive, featuring Amish Shah, who narrowly lost to Schweikert in 2024, and Marlene Galán-Woods, a former broadcast journalist. Galán-Woods, who was defeated by Shah in the 2024 primary, has secured the backing of the Democratic Congressional Campaign Committee (DCCC), signaling national party investment in her candidacy. Galán-Woods has faced criticism for her past as a registered Republican until 2018 and her previous support for GOP politicians. She has explained her shift by stating that "The Republican Party has been driven off a cliff by Donald Trump and people like (incumbent U.S. Rep.) David Schweikert," suggesting a disillusionment with the party’s current direction. The Democratic primary will test whether voters prefer a candidate with established party ties or one who represents a more recent conversion to the Democratic platform.
The eventual winners of both primaries in AZ-01 will face a fierce general election contest, with significant national resources poured into the district by both parties, underscoring its pivotal role in the House landscape.
Arizona’s 5th Congressional District: A Safe Republican Seat with Primary Intrigue
Andy Biggs’ departure from the 5th Congressional District (AZ-05) to pursue the governorship leaves an open seat in a reliably Republican district. Biggs won his last election in 2024 by over 20 points, and the district is ranked "Safe Republican" by Sabato’s Crystal Ball, meaning the Republican primary winner is highly likely to secure the general election.
The primary for AZ-05 has generated significant attention due to the high-profile candidates and recent controversies. Former Pinal County Sheriff Mark Lamb, who has cultivated an image as "America’s Sheriff" and is a strong proponent of conservative Christian values, quickly garnered former President Trump’s endorsement. Lamb’s campaign initially led in early polling, positioning him as the frontrunner.
However, Lamb’s campaign has been rocked by a multi-part investigation published by the Arizona Republic in May, alleging years of sexual misconduct, explicit messages, and abuse of power during his tenure as sheriff. The investigation also reported that Lamb was investigated by the Church of Jesus Christ of Latter-day Saints regarding these claims. Lamb’s campaign has vehemently denied the allegations, with his wife stating in a Facebook post that "a massive smear campaign is certainly not going to stop us from doing what’s right." Despite the allegations, former President Trump reaffirmed his support for Lamb last week, highlighting the enduring influence of the former president’s endorsements within the Republican base.
Challenging Lamb is wealthy construction owner Daniel Keenan, who has largely self-funded his campaign, pouring $1.6 million of his own money into the race. A recent poll backed by Keenan’s campaign, conducted by a GOP polling firm, showed him with a slim lead, suggesting the allegations against Lamb may be impacting voter sentiment. Keenan’s campaign strategy likely focuses on presenting himself as a credible, financially stable alternative, seeking to capitalize on any doubts voters might have about Lamb.
The AZ-05 primary is a test of the power of a presidential endorsement against significant personal allegations and a well-funded challenger. The outcome will not only determine the next representative for the district but also offer insights into the Republican primary electorate’s priorities and sensitivities. Three Democrats are also running in the primary, but they face an uphill battle in the general election against the heavily favored Republican nominee.
Broader Implications: Arizona’s Role in the National Political Landscape
The Arizona primaries in 2026 are more than just local contests; they are critical indicators of the state’s political direction and its potential impact on the national balance of power. The gubernatorial race will test Governor Hobbs’ ability to appeal to a broad, moderate electorate against a potentially more conservative and Trump-aligned Republican nominee. Her success or failure could provide a blueprint for Democrats in other swing states.
The congressional primaries, particularly in AZ-01, will have direct consequences for the control of the U.S. House. A Republican flip in AZ-01 could significantly aid the GOP’s chances of retaining or expanding their House majority, while a Democratic hold or gain would bolster their efforts. The outcomes in these districts will reflect national trends, voter engagement with specific policy issues, and the ongoing influence of former President Trump within the Republican Party.
Furthermore, the persistent focus on election integrity claims in these races underscores a continuing challenge for American democracy. How candidates navigate these discussions, and how voters respond, will offer insights into the public’s trust in electoral systems and the future trajectory of political discourse in the United States. Arizona’s primaries, therefore, are not merely selecting candidates; they are shaping narratives, testing political strategies, and setting the stage for one of the most closely watched general elections in the nation.
