Representative Wesley Bell and former Representative Cori Bush are facing each other in a primary rematch for Missouri’s 1st Congressional District. The contest centers on an ideological divide within the Democratic Party regarding the United States' relationship with Israel and the influence of outside spending in local elections.
The two candidates first met in a 2024 primary where Bell unseated Bush, who was an incumbent at the time. Bush was among the first members of Congress to characterize Israel’s military actions in Gaza as "genocide," a term both the U.S. and Israeli governments deny. In the current cycle, Bell holds the seat with endorsements from House Minority Leader Hakeem Jeffries (D-NY) and the Congressional Black Caucus PAC, while Bush is backed by Senator Bernie Sanders (I-VT) and the Democratic Socialists of America.
Financial transparency data from ad tracking firm AdImpact shows a significant spending gap between the candidates. United Democracy Project, a super PAC aligned with the American Israel Public Affairs Committee (AIPAC), has spent at least $2.1 million on advertising to support Bell. Bell’s own campaign has spent over $2 million, supplemented by $700,000 from the New Democrat Majority super PAC. In contrast, Bush’s campaign has spent less than $200,000 on advertising for this race.
A person living in the St. Louis area would notice a heavy volume of television and digital advertisements highlighting the candidates' records. Specifically, AIPAC-aligned ads have targeted Bush’s attendance record and her past criticism of the Biden-Harris administration. Conversely, Bush’s supporters, such as Justice Democrats, argue the race reflects a broader shift where nearly half of self-identified Democrats, according to a July AP-NORC poll, believe Israel has committed genocide. The outcome will determine whether the district favors a moderate incumbent who supports maintaining traditional ties with Israel or a progressive challenger who advocates for a fundamental shift in U.S. foreign policy.
The results of this primary, occurring alongside other contests such as a Senate primary in Michigan between Abdul El-Sayed and Rep. Haley Stevens, will set a precedent for how Democratic candidates manage ties to lobbying groups. Some potential 2028 presidential contenders have already begun rejecting AIPAC funding, suggesting the outcome in St. Louis could influence future national campaign strategies. Voters in the district will cast their ballots on Tuesday to decide the winner; if no further challenges arise, the primary winner will move toward the general election in November.
