Arizona voters head to the polls Tuesday to select their party nominees for two open House seats, setting the stage for competitive November contests that could influence the balance of power in Washington. The primaries feature a high-stakes Republican showdown between incumbent Reps. Andy Biggs and David Schweikert, who are vying for the GOP nod to take on Democratic Governor Katie Hobbs this fall.
Schweikert's seat in the 1st Congressional District is a prime pickup opportunity for Democrats, who are pouring resources into the race. The Democratic primary features state Representative Amish Shah and former news anchor Marlene Galan-Woods, both seeking to face off against Republican nominee Jay Feely, a former Arizona Cardinals football player backed by former President Trump. Feely's campaign has gained traction with Trump's endorsement, but the GOP field remains competitive.
Meanwhile, Biggs is vacating his seat in the deeply conservative 5th Congressional District, where former Pinal County Sheriff Mark Lamb is expected to secure the Republican nomination. Lamb, who also has Trump's endorsement, is heavily favored in the ruby-red district. The race highlights the ongoing influence of Trump in GOP primaries, as his backing has become a key factor in contested races across the state. For more on how Trump's sway is shaping these contests, see our Arizona primary preview.
The primary battle between Biggs and Schweikert has drawn national attention, as both are seasoned incumbents with conservative credentials. Biggs, a member of the House Freedom Caucus, has positioned himself as a staunch conservative, while Schweikert, a more moderate Republican, has emphasized his work on fiscal issues. Their clash reflects broader divisions within the GOP, with Trump's endorsement playing a pivotal role in the race.

Democrats see the 1st District as a key target, given its competitive nature and the potential to flip a seat that has been held by Republicans. The outcome of the Democratic primary will determine who faces Feely in November, with both Shah and Galan-Woods bringing distinct strengths. Shah, a state lawmaker, has focused on healthcare and education, while Galan-Woods, a former news anchor, has emphasized her communication skills and moderate appeal.
In the 5th District, Lamb's path to the nomination appears clear, but the general election is expected to be less competitive given the district's strong Republican lean. However, the race could still have implications for control of the House, as every seat matters in the closely divided chamber.
Polls close at 10 p.m. EDT, and results are expected to come in quickly. Decision Desk HQ will provide live updates as votes are tallied.
