A Democratic civil war is breaking into the open, with progressives accusing party leaders of trying to sink their own candidates over Israel — bad news for party unity ahead of a key Senate race.

• Four Democrats pushed a resolution attacking the Democratic Socialists of America; Ro Khanna says it was a smear aimed at candidates who criticize Israel.
• The fight centers on Michigan, where Abdul El-Sayed's Senate run is drawing harder attacks from Democrats than from Republicans.
• Pro-Israel donor money is the alleged driver, along with fear that a progressive win in a swing state destroys the establishment's "only we can win" argument.
• Party leadership decisions — a Jeffries meeting with Jared Kushner, and putting a strongly pro-Israel member atop the Middle East subcommittee — are being read as a signal to the base, which now views Israel unfavorably by a wide margin.
• Khanna, who was held for over an hour by armed settlers in the West Bank, wants US aid to Israel cut off entirely after an NBC crew was attacked there.

Outlook: The Michigan Senate primary becomes the test case for whether progressives can win a swing state without their own party's backing.
