Arizona Republicans vote for a candidate to take on Gov. Katie Hobbs, and more races to watch today

Key Points:

• Arizona voters are heading to the polls Tuesday for primaries that will determine the Republican challenger to Democratic Gov. Katie Hobbs, as well as key congressional races amid a contentious battle for control of the U.S. House.
• Gov. Hobbs is unopposed for the Democratic nomination, while the GOP primary features four candidates, with Reps. Andy Biggs and David Schweikert as frontrunners; Biggs, endorsed by former President Trump, leads early polls and is a prominent proponent of Trump's 2020 election fraud claims.
• Election integrity and voter fraud claims remain central themes in the governor's race, with research indicating significant voter distrust in absentee and mail-in ballot processes, influenced by persistent unfounded allegations from political leaders.
• In Arizona's 1st Congressional District, a competitive GOP primary includes Trump-backed former kicker Jay Feely, while Democrats back Marlene Galán-Woods, who faces scrutiny over her prior Republican affiliation; the district is considered a toss-up in 2024.
• The open 5th Congressional District seat, vacated by Biggs running for governor, features a GOP primary where Trump supports former Sheriff Mark Lamb despite sexual misconduct allegations, while wealthy challenger Daniel Keenan leads in recent polling; the district is safely Republican for November.
