Wesley Bell holds a clear lead in the Missouri 1st District Democratic primary as the incumbent who defeated Cori Bush in 2024, bolstered by strong fundraising totals exceeding $1.9 million compared to her roughly $845,000 and continued backing from outside groups. A February 2026 poll showed Bell ahead 44 percent to 40 percent with 17 percent undecided, underscoring his edge in a majority-Black district where local economic concerns often outweigh foreign policy debates. Bush, who filed to run in February after announcing her rematch bid last October, draws support from progressive voters and labor endorsements but confronts the challenges of reclaiming a seat against an established incumbent with a stronger voting attendance record. The August 4 primary date leaves several months for campaign developments to influence the outcome.
