Rep. Wesley Bell has defeated former Rep. Cori Bush in the Missouri Democratic primary, securing his hold on the St. Louis-area congressional seat for a second time. The result ends Bush's bid to reclaim the seat she lost to Bell in the 2024 primary, making her one of the few congressional incumbents at the time to fall to a primary challenger.

Bell, who first ousted Bush in 2024 amid her federal corruption indictment, consolidated his position as the district's Democratic nominee. His victory signals continued Democratic voter preference for the former St. Louis County prosecutor over the progressive activist who rose to national prominence as a member of the Squad.

The race attracted substantial outside money from opposing directions. AIPAC, the pro-Israel lobbying organization, backed Bell, while progressive groups affiliated with the Democratic Socialists of America supported Bush's comeback attempt. The contest became a proxy battle between the centrist and progressive wings of the Democratic Party.

Bush had sought to frame her return bid around grassroots activism and progressive policy priorities, but Bell's incumbency advantage and fundraising edge proved decisive. The outcome further consolidates a pattern of AIPAC-backed candidates prevailing over progressive challengers in competitive Democratic primaries.
