Jamaal Bowman’s Election Loss: 5 Takeaways

Representative Jamaal Bowman of New York became the first member of the House’s progressive “squad” to lose a seat in Congress on Tuesday, dealing a stinging defeat to the Democratic left after a brutal intraparty fight.

The contest on the outskirts of New York City centered on Democrats’ disagreements over Israel’s war in Gaza. Progressive groups raced to try to save Mr. Bowman, a leading voice against the war. Pro-Israel political groups pumped record-shattering sums into defeating him.

But by the end, it devolved into a broader spat over race and class that tested the Democratic coalition. Mr. Bowman’s opponent, the Westchester County executive, George Latimer, also benefited from old-fashioned local alliances and a series of embarrassing missteps by the incumbent.

Here are five takeaways from the results.

AIPAC notched its first big win.

After the Oct. 7 Hamas-led attacks, political groups aligned with Israel issued a message to its critics like Mr. Bowman: Moderate your views or prepare for stiff political opposition.

Tuesday’s result showed that was no idle threat.

The American Israel Public Affairs Committee, Democratic Majority for Israel and other affiliated organizations ultimately spent more than $16 million to defeat Mr. Bowman, more than any outside group has ever put into a House race.
