Rep. Cori Bush, a prominent member of the progressive 'Squad', lost her Democratic primary in Missouri's 1st Congressional District to St. Louis County Prosecutor Wesley Bell, marking the second defeat for the group this year amid significant pro-Israel campaign spending. Bell secured 51% of the vote compared to Bush's 46%, bolstered by over $8 million from the American Israel Public Affairs Committee's super PAC, which targeted Bush due to her vocal criticism of Israel's actions in Gaza. This loss follows a similar outcome for Rep. Jamaal Bowman in New York, underscoring a trend where pro-Israel advocacy groups are channeling substantial funds against progressive lawmakers. Bell emphasized his commitment to the district and criticized Bush's performance, while Bush defended her record and community ties. With strong Democratic backing, Bell is favored to retain the seat in the upcoming general election. The primary results reflect ongoing divisions within the Democratic Party regarding foreign policy and progressive values.
