Voters across Arizona will cast ballots on Tuesday to choose nominees for governor and several U.S. House seats, in a primary that could set the tenor for competitive general election fights this fall in a state long regarded as politically volatile. Republicans hold a registration edge in Arizona, but the state’s substantial independent electorate has long made it a battleground where party control can shift quickly.

One of the most closely watched contests centers on the open seat in Arizona’s 1st Congressional District, a Phoenix-area district where Representative David Schweikert is leaving the U.S. House at the end of the year as he pursues the Republican nomination for governor. With that seat vacated, Democrats have made it a top priority as they seek the net pickups needed to win control of the House. Republicans currently occupy 218 House seats compared with 212 for Democrats, not counting one independent who caucuses with Republicans and four vacancies; Democrats need a net gain of four seats to secure a majority beginning in 2027.
On the Republican side in the 1st District, former professional football kicker Jay Feely, who counts President Donald Trump among his backers, faces challengers for the party nomination. One of those challengers, Joseph Chaplik, is a former state legislator who has aligned himself with the Arizona Freedom Caucus, a far-right faction within the state party. Another contender, John Trobough, a technology firm executive, describes himself as a "Reagan conservative," a label that positions him somewhat away from the most conservative elements in the field.
The Democratic primary in the 1st District pits Marlene Galan-Woods, a former Republican and ex-broadcast journalist backed by the party’s establishment, against Amish Shah, an emergency room physician who narrowly defeated Galan-Woods for the nomination in 2024. Galan-Woods has drawn support from figures including U.S. Senator Mark Kelly and the Democratic Congressional Campaign Committee. Shah won the Democratic nomination in 2024 but lost in November to Schweikert by a margin of 51.9% to 48.1%; the 2024 general election result and past presidential outcomes make the district a toss-up again this year, with Joe Biden having carried it in 2020 and Donald Trump winning it in 2024.
Beyond the 1st District, the 6th Congressional District is also viewed as competitive heading into November. The seat is currently held by Republican Representative Juan Ciscomani, who faces no primary opposition, while JoAnna Mendoza is the lone Democrat on the primary ballot for that district. Both parties see the 6th as a potential pickup target depending on how nominating contests unfold and how candidates fare in the fall campaign.
At the top of the statewide ticket, Democratic Governor Katie Hobbs, who has no primary opponent, is preparing for a general election rematch against the Republican nominee. The Republican gubernatorial primary includes U.S. Representative David Schweikert and U.S. Representative Andy Biggs among a four-person field vying to challenge Hobbs. Biggs, who has led in many early measures of the GOP race, is a prominent conservative and was identified by the Cook Political Report when it adjusted its forecast on the Arizona governor’s race from a toss-up to "lean Democratic." The report cited Biggs’s status as a 2020 presidential election denier and described him as a potentially polarizing figure in the swing state.
Images from recent campaign stops illustrated the intensity of the Republican contest. Supporters at a Biggs campaign event in Arizona raised 'Biggs Governor' signs during a Republican primary rally.

Republicans and Democrats alike are watching the gubernatorial outcome closely because the nominee who emerges will face Hobbs in November in what could be a competitive statewide contest. Party strategists and outside analysts have emphasized how the choice of a nominee in a primary can affect general election prospects, particularly in a state with substantial numbers of unaffiliated voters. For Democrats, the prospect of facing a far-right nominee statewide is viewed as one pathway to retaining or expanding influence both in the governor’s office and in closely contested U.S. House races.
Other House contests across Arizona are also on the national radar. Republicans currently hold a number of seats in the state, but several have been designated as competitive by analysts and could be in play depending on primary outcomes and the national environment later this year. One such target for Democrats is the 2nd District, held by Republican Representative Eli Crane, which is among the races Democrats hope to contest aggressively in November. The final composition of the November ballot in Arizona will be shaped by the results of Tuesday’s primaries, a set of contests that Republicans and Democrats are treating as critical to their broader strategies heading into the midterm elections.
As ballots are counted and winners are certified in the days after the primary, attention will turn quickly to the fall campaign calendar. Candidates who secure their party’s nomination will begin pivoting to the general election, while national and state political committees will assess where to commit resources. With control of the U.S. House within reach if Democrats can net four seats, and with the Arizona governorship potentially up for grabs depending on Republican nominee selection, the outcomes of these primaries carry implications that reach beyond state lines.
The primary day in Arizona is therefore being watched not just for the winners it produces but for how those nominations shape the strategic map for November — which incumbent members will be defended, which open seats will become priority targets, and which general election matchups will dominate a cycle that national stakeholders see as consequential for control of Congress and for the political direction of a key swing state.
Primary results show Rep. Andy Biggs defeating Rep. David Schweikert to clinch the Republican nomination for governor, setting up a November matchup against incumbent Katie Hobbs, according to projections from ABC15 Arizona. In the 1st Congressional District, Trump-backed Jay Feely won the GOP primary while Marlene Galán-Woods took the Democratic nomination.
The primary took place on July 21, 2026, with county election officials posting unofficial returns that night and major outlets projecting winners in key contests.

Pinal County Sheriff Mark Lamb won the Republican primary for the conservative seat being vacated by Andy Biggs, a race that drew national attention and a presidential endorsement.
Heading into the primary Arizona had about 4.3 million registered voters — roughly 1.5 million Republicans, 1.2 million Democrats and about 1.5 million unaffiliated voters — a large independent bloc that election analysts say keeps statewide races competitive.
Under Arizona’s recently implemented system, party nominees have until early September to select running mates for the newly created, separately elected lieutenant governor position, the first time that office will appear on a general-election ticket in the state.
