Stanton Defeats Democratic Socialist Challenger In Arizona Primary

One of the Democratic Party’s most closely watched primary battles has ended with a decisive victory for an incumbent congressman, despite an aggressive challenge from the party’s progressive wing.

The race had drawn national attention as another test of whether candidates running on an anti-Israel platform could unseat more established Democrats.

Rep. Greg Stanton easily defeated democratic socialist challenger Kai Newkirk in Arizona’s Democratic primary Tuesday, securing the nomination for another term in Congress with a commanding margin.

With nearly all votes counted, Stanton received about 68.1% of the vote compared with Newkirk’s 31.9%, according to multiple media outlets.

The victory sends Stanton, a former Phoenix mayor first elected to Congress in 2018, into November’s general election, where he is expected to face Republican Zuhdi Jasser.

Following the race, Stanton described the outcome as a choice about the future direction of the Democratic Party.

“This campaign presented voters with a real choice about how Democrats should lead,” Stanton said in a statement posted to his campaign page.

“Tonight, the voters chose proven leadership that fights back, delivers real results, and brings our party together.”

Throughout the campaign, Newkirk attempted to make U.S. support for Israel the defining issue in the race.

He repeatedly criticized Stanton for receiving support from the American Israel Public Affairs Committee, commonly known as AIPAC, and accused the organization of wielding too much influence in American politics.

Newkirk also pointed to a multimillion-dollar public messaging campaign promoting Israel as evidence of what he characterized as outside influence in U.S. elections.

Among his policy positions, Newkirk called for ending U.S. military aid to Israel and imposing an arms embargo on the country.

He also sharply criticized Stanton after the congressman voted against an amendment offered by Rep. Thomas Massie, R-Ky., that would have reduced military assistance to Israel.

“Greg Stanton has taken over $300K from AIPAC,” Newkirk wrote during the campaign.

Stanton defended his vote, arguing that reducing military assistance would weaken America’s ability to counter threats from Iran while also acknowledging that changes in Israeli leadership and policy would be necessary as the current U.S.-Israel security agreement approaches its 2028 expiration.

Although Stanton has supported continued military assistance to Israel, he has also publicly criticized Israeli Prime Minister Benjamin Netanyahu on multiple occasions.

Newkirk received endorsements from several progressive organizations, including Our Revolution, Progressive Democrats of America and Track AIPAC.
