Rahm Emanuel said a new wave of Democratic socialists "do not like America" and warned their rise would hurt Democrats nationally, sharpening his critique as his own 2028 prospects draw attention.
Three candidates backed by New York City Mayor Zohran Mamdani won upset primaries in late June, with Emanuel arguing victories in deep-blue areas do little to help Democrats retake the White House.
Emanuel said the party must flip red areas to blue rather than make blue districts "deeper blue," pointing to places like Michigan's Upper Peninsula as the kind of terrain Democrats need to win.
James Carville has already pushed the dispute further, calling for Democrats to discuss a formal "schism" after denouncing candidate Darializa Avila Chevalier's rhetoric and saying he is not in the same party.
