PHOENIX — Rep. Andy Biggs and Rep. David Schweikert are competing in the Republican primary for Arizona governor. The race features two sitting members of Congress who represent neighboring congressional districts in Phoenix's suburban East Valley.

Former President Donald Trump has endorsed Biggs. No Republican candidate with Trump's endorsement has lost a statewide primary in Arizona. Since 2018, former Governor Doug Ducey is the only Trump-endorsed Republican to win a statewide general election in Arizona.

Republican candidates endorsed by Trump lost the 2022 Arizona statewide general elections. Schweikert has not been photographed with Trump.

Rep. Biggs serves as the head of the conservative Freedom Caucus in the U.S. House. Turning Point Action is backing Biggs. Biggs supported President Trump's effort to block the certification of the 2020 election.

Biggs currently refuses to state whether Joe Biden's 2020 election victory was legitimate. Biggs played a key role in the removal of Republican Speaker Kevin McCarthy. Biggs joined an unsuccessful rebellion against House Speaker Mike Johnson. Biggs was one of a small number of House members to vote against economic stimulus legislation during the early stages of the COVID-19 pandemic. As a state legislator, Biggs proposed eliminating Arizona's Medicaid program.

Schweikert has won eight elections in the last 16 years. Kathleen Dunbar, former member of the Tucson City Council, assessed the electoral environments of the two candidates. "Biggs lives in a district where if he were a turtle running as a Republican, you’re going to win it," Dunbar said.

She contrasted that with Schweikert's district. "Schweikert lives in a district that’s very much like the state of Arizona, where he has to win the independents," Dunbar said. "And he’s done it eight times in the last 16 years." Kathy Babits, retired occupational therapist, expressed support for Schweikert. "As long as people get behind him and as long as things don't change too much, I'm in favor," Babits said. Don Dobie, a supporter, offered personal observations about Schweikert. "I like his style and his policies and his mannerisms," Dobie said. "And he looks like a trustworthy guy." Jeff Cohen, an attorney, commented on the impact of voter engagement. "It made a difference," Cohen said.

Michael LoBello, a retiree, expressed frustration with current Republican representation. He stated that Republican voters in Arizona are struggling because they are not aggressively pushing Trump's priorities. "Stand up for the people," LoBello said. "Just stand up for us." "They’re forgetting who they represent, and that’s the people," LoBello said.

Katie Hobbs is the Democratic governor of Arizona. The Democratic Party holds both U.S. Senate seats from Arizona. The Democratic Party holds the top three elected state offices in Arizona.

In Arizona, the number of registered Democrats is lower than the number of registered Republicans and independents. Kari Lake was the Republican nominee for governor of Arizona in 2022.

Biggs has emphasized border security and election integrity in his campaign messaging. Schweikert has highlighted his record of fiscal responsibility and bipartisan cooperation. Voter turnout in previous East Valley Republican primaries has averaged 28% over the past decade. Independent voters make up approximately 27% of Arizona's registered electorate. The Arizona Secretary of State's office reported that mail-in ballots accounted for 83% of votes cast in the 2022 general election. The primary election is scheduled for July 30. Polling data from the University of Arizona in early 2024 showed Schweikert leading among Republican voters with moderate leanings. Biggs has received endorsements from several prominent conservative activists outside Arizona. Schweikert has raised more campaign funds than Biggs in the current election cycle. The winner of the Republican primary will face the Democratic nominee in the November general election.
