Former Rep. Cori Bush is trying to reclaim her Missouri congressional seat by attacking her successor's pro-Israel ties, part of a broader socialist push to unseat establishment Democrats nationwide.
Bush, a member of the Democratic Socialists of America and one of the most outspoken members of the now-diminished "Squad," is challenging incumbent Rep. Wesley Bell in Missouri's 1st Congressional District primary. The race has become a proxy fight over Israel policy, AIPAC influence, and whether the Democratic Party's left flank can claw back ground it lost in 2024.
The former two-term congresswoman lost her seat to Bell, a former county prosecutor, and has blamed that defeat squarely on outside spending by pro-Israel groups affiliated with AIPAC. She claims hundreds of thousands of dollars poured into the district from beyond its borders to defeat her. Now she wants a rematch, and she is making Bell's relationship with pro-Israel donors the centerpiece of her campaign.
Bush's latest campaign ad, released ahead of the primary, accuses Bell of neglecting his constituents after a devastating tornado struck St. Louis in May 2025. The storm caused what Bush described as $1.6 billion in damages and took several lives. Rather than focusing on recovery, Bush charged, Bell left the country.
Fox News Digital reported that Bush posted on X alongside the ad:
"When the disaster caused $1.6 billion in damages and took several lives, Wesley responded by hopping on a flight to Israel funded by Trump's donors less than 90 days later."
The accusation is pointed but rests entirely on Bush's characterization. The reporting does not include independent confirmation of the trip's timing, its funding source, or whether "Trump's donors" is an accurate description of whoever paid for it. Bush's framing treats the trip as a betrayal. Bell's campaign treats her attacks as noise.
In an earlier post on X, Bush went further, calling Bell "a former Republican campaign manager who is bought and paid for by AIPAC" and pledging to return to Washington "with no corporate cash or AIPAC-funded trips." She pointed to an August 4th date as the primary.
Bell's campaign responded by pointing to his debate performance on St. Louis Public Radio, where he laid out his tornado response in detail. Bell told the debate audience that he went to work immediately after the storm hit, both on the ground and in Washington, working a delegation that includes six Republicans and only two Democrats.
"I got on the phone with each one of them. Sometimes that meant sitting in their offices as well, to explain to them how important it was for them to join me in making certain that St. Louis got the resources that folks here needed."
Bell said he secured over $200 million and counting in FEMA disaster relief for the area, a figure his campaign has highlighted as evidence that he delivered results while Bush delivered rhetoric. His campaign also shared an ad with Fox News Digital featuring a constituent who dismissed Bush's attacks as "just politics."
Another constituent in the Bell ad offered a different kind of endorsement: "Wesley Bell's taken on Trump. He's fighting for me and my neighbors." That framing, positioning Bell as both a Trump opponent and a pragmatic dealmaker, is designed to hold moderate Democratic voters who have no appetite for Bush's brand of socialist politics.
Bush's comeback bid does not exist in isolation. It sits inside a wave of primary challenges by Democratic Socialists of America members targeting establishment Democrats from coast to coast. DSA candidates are running in gubernatorial races in Wisconsin, a Senate race in Michigan where a DSA member reportedly leads a Democratic primary, and House races in multiple states.
In New York and Colorado, DSA-aligned candidates have already toppled sitting House Democratic incumbents. One recent Colorado race saw a democratic socialist unseat a 15-term Democrat, the kind of result that would have been unthinkable a decade ago.
The pattern is consistent: DSA challengers run to the left on Israel, corporate money, and economic policy, then frame the incumbent as a sellout. Whether voters reward that framing or punish it depends on the district. In Bush's case, voters rejected it once already.
On Inauguration Day in January 2025, DSA members marched in Washington carrying signs that read "SOCIALISM BEATS FASCISM." The slogan captures the movement's self-image, but it also captures the gap between DSA's rhetoric and the preferences of rank-and-file Democratic voters who keep electing the candidates DSA wants to replace.
That internal tension has produced open confrontations. Socialist activists have directed "you're next" chants at House Democratic leader Hakeem Jeffries, signaling that no one in the party's leadership is safe from a primary challenge. The message is less a political strategy than a declaration of factional hostility.
The fracture inside the Democratic Party over U.S.-Israel relations has only deepened since the Hamas attack on Israel on October 7, 2023. Bush was among the most vocal critics of Israel's military response, previously accusing Israel's government of waging what she called a genocide against Palestinians in Gaza, a characterization that remains her claim, not an established legal finding.
During her time in Congress, Bush consistently voted against emergency funding for Israel, placing her on the far edge of her own party. That position cost her politically in 2024, when pro-Israel groups poured resources into her district to support Bell. But it also built her a following among progressive activists who view AIPAC's influence as a corruption of democratic politics.
Bell, by contrast, represents the more pragmatic wing of the party, willing to work across the aisle with Republicans on disaster relief, willing to accept pro-Israel support, and willing to frame himself as a fighter against Trump rather than against the Democratic establishment. The contrast between the two candidates mirrors a split playing out in New York primaries and other races where anti-Israel sentiment has become a mobilizing force on the left.
Not every Democrat is sympathetic to the DSA's posture. Sen. John Fetterman has openly clashed with Democratic Socialists over Israel policy, making clear that the party's pro-Israel mainstream has no intention of ceding ground quietly.
Bush faces a fundamental problem: she is asking the same electorate that removed her to put her back. Her argument is that outside money, not voter preference, drove her loss. If that is true, and if she can neutralize AIPAC spending this cycle, she has a case. If voters simply preferred Bell's approach, no amount of populist messaging about corporate cash will change the math.
Bell, for his part, has a tangible record to run on. Over $200 million in FEMA disaster relief is not an abstraction, it is money flowing into a community that lost lives and sustained billions in damage. Whether voters credit Bell for that work or accept Bush's framing that he abandoned them for an AIPAC-funded trip will likely decide the race.
The broader question is whether the DSA's strategy of serial primary challenges can sustain itself. Picking off a long-tenured incumbent in a low-turnout race is one thing. Defeating a sitting congressman who can point to concrete federal dollars delivered after a natural disaster is another. Bush's campaign will test whether anti-Israel energy and anti-establishment anger are enough to overcome a record of constituent service, or whether voters in Missouri's 1st District have already given their answer.
Democrats who keep telling voters the real enemy is outside their party may eventually discover that voters were listening, and drawing their own conclusions about who is actually fighting for them.
