Missouri Democrat Wesley Bell won a primary election on Tuesday against former Representative Cori Bush, who is affiliated with the Democratic Socialists of America. This marked the second time the two candidates have faced each other since 2024, with Bush attempting to reclaim her congressional seat. Bell differentiated himself by presenting a more moderate yet still progressive platform.

The contest reflected broader fractures within the Democratic Party between its moderate wing and its further-left insurgent faction. Observers characterised Bell's win as a significant achievement for establishment-aligned Democrats in what amounts to an internal party struggle over ideological positioning and electoral strategy heading into upcoming elections.
