Cori Bush is running to reclaim her U.S. House seat in Missouri's 1st Congressional District. After losing to incumbent Wesley Bell in last year's primary, she is now challenging him again for the Democratic nomination in what has become one of the more closely watched races in state politics.

Betting markets currently favor Bell to win the matchup. His probability stands at 67.5%, up slightly over the past week. Bush's chances sit at 33%, though her campaign appears to be picking up momentum as the primary unfolds. The shift suggests her team has been gaining ground through endorsements and voter outreach efforts.

Both candidates carry significant backing from outside groups and have run intense campaigns. Bell's incumbency and fundraising advantage remain substantial. Yet the race remains competitive enough that late endorsements or turnout patterns could still shift the outcome before votes are fully counted. Early results will be closely watched to see whether Bush can close the gap or if Bell's position holds firm through election night.
