Senator John Fetterman is drawing fierce criticism from progressives for making support for Israel his top political priority, even as more Democrats break with him.

• Fetterman clashed with Jon Stewart, refusing to back candidates who agree with him on the economy but disagree on Israel, prompting Stewart's line that "that's not our country."
• Critics say Fetterman ignores Pennsylvania problems like people who can't afford groceries, prescriptions, or health insurance while focusing on a foreign government.
• The number of House Democrats voting to block weapons to Israel has jumped from a handful to over 100, and Fetterman says he'd leave the party if it turned against Israel.
• Polls cited show most Jewish Americans oppose the current Israeli government, undercutting claims that pro-Israel politicians speak for them.
• Fetterman's approval among Pennsylvania Democrats has collapsed, with most saying they want to vote for someone else.

Outlook: The Democratic split over Israel is widening, and Fetterman faces a tough path to re-election as progressive challengers gain ground.
