Cori Bush, once a member of Congress, is seeking to reclaim her political position in Missouri. She faces Representative Wesley Bell, who previously defeated her in a primary a few years ago. The upcoming statewide primaries, scheduled for August 4, serve as a prelude to November’s midterm elections. St. Louis will be a decisive ground for the progressive movement, which has already achieved success in cities like New York City, Philadelphia, and Denver.
Missouri’s 1st District Race
In Missouri’s 1st District, voters will witness a rematch between the moderate Wesley Bell and Cori Bush, a strong progressive voice. Bush, who served this district from 2021 to 2025, was unseated by Bell, a local prosecutor. The previous race involved significant financial involvement from groups such as AIPAC’s United Democracy Project. Bell targeted Bush’s decision to vote against President Biden’s bipartisan infrastructure bill during their last contest.
Progressives support Bush with the hope that dynamics have shifted since 2024. Frustration with the Democratic establishment’s approach, particularly regarding former President Donald Trump, has led voters to favor progressive leaders in recent primaries. The primary will act as a barometer of the current sentiments among Democratic voters as the midterms approach.
Polling and Prediction Markets
Limited polling on this district, centered around St. Louis, has been made public. A single internal poll from Bush’s campaign showed Bell slightly leading. The poll indicated 44 percent support for Bell compared to 40 percent for Bush, with 17 percent of voters undecided. Additionally, Bush had a slightly more favorable view from voters than Bell.
Prediction markets show a lean towards Bell winning the primary. Kalshi gives him a 59 percent probability, while Bush’s chances are at 40 percent. This marks a change from a previous month when Bush had a slight advantage. On Polymarket, Bell’s likelihood of winning stands at 64 percent. These markets, where traders buy and sell contracts based on political outcomes, provide probability estimates but do not guarantee future results.
The November election appears favorable to the primary winner, as the district leans heavily Democratic. In 2024, Trump lost this district by a significant margin.
Endorsements and Campaigns
Cori Bush has rallied support from well-known progressives. Endorsements from Vermont Senator Bernie Sanders and Michigan Representative Rashida Tlaib, along with backing from the organization Justice Democrats, bolster her campaign. On the other hand, Wesley Bell has gained support from House leadership figures like Minority Leader Hakeem Jeffries. AIPAC is again endorsing Bell, highlighting him as “Pro-Israel Incumbent.”
Reflecting on the 2024 Primary
The 2024 primary was marked by substantial spending from groups like AIPAC, which contributed over $8 million aiming to defeat Bush. Bush faced opposition for her stance against U.S. military aid to Israel following aggression in Gaza the previous year. Pew Research Center conducted a survey indicating a decrease in favorable views among Democrats towards Israel, marking a decline from 2024’s sentiments.
Bush’s campaign emphasizes her past achievements in Congress, claiming progress in funding, housing, and foreign policy. Despite being previously ousted, she insists on her commitment to the issues faced by St. Louis residents. Bell challenges her seriousness as a candidate, focusing on his dedication to the needs of local citizens.
Both political figures share roots in the Black Lives Matter movement. Bush was notable as an activist, while Bell served as a prosecuting attorney and was involved with the Ferguson City Council.
Recent Progressive Primary Wins
Progressives have achieved several key primary victories in recent times. In New York, Claire Valdez gained an open seat, replacing long-serving Representative Nydia Velázquez. Progressive challengers in New York also managed to unseat incumbents, with Brad Lander and Darializa Avila Chevalier securing wins. In Denver, Democratic socialist Melat Kiros defeated incumbent Diana DeGette. Other progressive wins occurred in Pennsylvania, New Jersey, and Texas, with these candidates expected to do well in the November elections.
