Democratic Rep. Cori Bush became the second member of the Squad to lose her primary when District Attorney Wesley Bell defeated her in a grueling and costly race Tuesday night.

Pro-Israel groups spent enormous sums of money to unseat Bush in the district where she won a surprise victory over a long-time incumbent Democrat in 2020.

The United Democracy Project, a super PAC of the American Israel Public Affairs Committee, spent $9.2 million against Bush, according to AdImpact, making the primary the second-most expensive of the year after the UDP spent millions to fight fellow squad member Jamaal Bowman of New York.

By comparison, Bush’s campaign spent just $1.1 million and the Justice Democrats, a group that supports left-wing candidates, spent just $2.5 million in the district, which includes St. Louis.

The massive campaign by pro-Israel groups appeared to pay off, as Bell declared his winner on Tuesday night with 51 percent of the vote compared to 46 percent for Bush.

“I am committed to serving the St. Louis region in Congress with integrity, transparency and dedication,” he said in a statement. “Together, we will tackle the challenges ahead and build a community where everyone has the opportunity to succeed.”

Meanwhile, Bush vowed in a speech at her election party that she would take care of her people, whether she was a member of Congress or not.

Bush is one of several Democrats who called for a ceasefire after Hamas launched a surprise attack on Israel on Oct. 7 that killed 1,200 people and prompted Israel to respond with a military campaign that killed nearly 40,000 people in the Gaza Strip.

She and many of her fellow Democrats boycotted Israeli Prime Minister Benjamin Netanyahu’s joint address to Congress last month. Bush also boycotted Israeli President Isaac Herzog’s joint address to Congress before the October 7 attack.

But the United Democracy Project’s ads made no mention of Israel, only the fact that she voted against the bipartisan 2021 infrastructure bill, arguing that she was an ineffective lawmaker who regularly got in the way of President Joe Biden.

Bush actually voted against the bill because she feared that passing the bill without Build Back Better – the Democrats’ proposed social spending bill that they hoped to pass along party lines – would result in the bill’s failure. This came when Senator Joe Manchin, who later left the Democratic Party, announced his opposition.

Bush, for her part, made clear her support for abortion rights and cooperation with the Biden administration.

Bush, like many of her squad colleagues, sought a more confrontational style of Democratic politics and described herself as a “politician.” When an eviction moratorium went into effect in 2021 amid the Covid-19 pandemic, Bush led a sit-in on the steps of the Capitol, prompting the Biden administration to extend the moratorium until it was overturned by the Supreme Court.

At the same time, Bush continued to face questions about the fact that the Justice Department was investigating her.

Bush’s defeat came after his squad colleague Jamaal Bowman lost his seat in June in the most expensive primary race for the House of Representatives in history.

Like Bush, Bowman had a candidate in the race, George Latimer, who was showered with unprecedented amounts of money by pro-Israel groups.

Other members of the Squad have managed to survive their primaries. Rep. Summer Lee defeated a rival in Pennsylvania earlier this year, while Rep. Alexandria Ocasio-Cortez of New York easily swept her challengers in the primary.
