A rising progressive House candidate in Colorado stumbled into a fight on the left after seeming to defend Israel and smear right-wing critics as anti-semites, then quickly reversed course — a messy moment for the anti-war coalition.

• Milot Kiros, who won an upset primary running hard against Israel and its war in Gaza, said her big worry was Israel "losing support" in the US, drawing backlash from her own base.
• She also argued left-wing critics of Israel oppose it for good reasons, while right-wing figures like Tucker Carlson and Candace Owens only pretend to care about Palestinians to mask bigotry.
• After the blowback she walked it back, saying she "fumbled the line," and restated her opposition to US funding for Israel and to conflating anti-Zionism with anti-semitism.
• Critics on the left suspect her sudden shift came from party pressure, warning AIPAC money will flood to Republicans in the general election unless she softens her tone.
• The underlying pitch is a left-right anti-war coalition that sets aside domestic fights to rein in US foreign policy and endless wars.

Outlook: Expect more friction as anti-war voices on the left and right test whether they can actually work together heading into November.
