A public clash between Congressman Ro Khanna and pro-Israel groups is escalating, a sign that the lobby's grip on US politics is weakening.

• Khanna is being publicly attacked as anti-Semitic by pro-Israel figures after he backed cutting off aid to Israel.
• Progressive candidates who ran on no aid to Israel, taxing billionaires, and Medicare for All won recent races despite big money against them.
• The counterattack leans on calling critics bigots, a tactic that is losing its power as more Americans turn against funding the war.
• Netanyahu is blamed for pulling the US into the Iran conflict, which pushed gas and food prices higher.
• The pro-Israel lobby remains one of the biggest donors to federal politicians in both parties.

Outlook: Expect more Democrats to break with the party line on Israel as the political cost of defending it keeps falling.
