Wesley Bell defeated Cori Bush in Missouri’s Democratic primary for the 1st Congressional District on August 4, advancing to the general election as the party’s nominee in a safely blue seat representing St. Louis. Bell, a former St. Louis County prosecutor, won the rematch against Bush, the former U.S. representative and progressive “Squad” member, in a race that tested Democratic divisions over Israel policy and the influence of pro-Israel groups in primary elections.
The primary centered on Bush’s criticism of Bell’s acceptance of support from pro-Israel organizations. Bush, who lost to Bell two years earlier in a close contest, framed the 2026 race as a referendum on whether voters wanted their party to be shaped by the American Israel Public Affairs Committee (AIPAC) and its affiliated groups.
Bell’s campaign focused on economic issues, according to his platform calling for holding the Trump administration accountable, expanding affordable health care access, lowering energy costs, and creating jobs in St. Louis. He received endorsements from Democratic leadership, including House Democratic Leader Hakeem Jeffries and the Congressional Black Caucus PAC.
The 2024 Defeat and AIPAC’s Role
Bush’s path to a comeback bid was shaped by her narrow 2024 primary loss to Bell, who defeated her 51.1% to 45.6% in a field of four candidates. During that race, AIPAC’s affiliate organization, the United Democracy Project (UDP), spent approximately $8.5 million either against Bush or in support of Bell. Bush attributed her 2024 loss to the spending by pro-Israel groups and vowed to challenge Bell again.
In the 2026 race, the UDP spent $2.5 million as of late July, according to reporting on campaign finance. Bush received endorsements from U.S. Senator Bernie Sanders, Our Revolution, and the Democratic Socialists of America, signaling the contest’s role as a proxy battle over the party’s ideological direction.
Missouri voters decided primary races and amendments on August 4, with Bell’s victory in the 1st District race representing another setback for progressive candidates in 2026. The race was rated as safely Democratic for the general election, meaning the primary winner is heavily favored to win the seat in November.
