A look at how Democratic-socialist candidates are racking up wins and topping popularity polls, which is bad news for the party's establishment wing and its donors.

• Barstool's Dave Portnoy is teasing a run for NYC mayor against Zohran Mamdani, but dismisses the voters as "young white Ivy League girls" — a misread, since the winning coalition is young, multi-racial, and working-class.
• Mamdani is now one of the most-liked figures among Democratic voters, ranking just behind Barack Obama and Bernie Sanders; no Republican rates highly except Marco Rubio.
• DSA and progressive candidates are winning real races — Brad Lander beat Dan Goldman in a heavily Jewish Manhattan district, and similar wins are landing in DC.
• A big driver is Israel: voters are rejecting establishment Democrats who back the war, and attacks calling critics "Nazi collaborators" are losing their punch.
• The establishment's "electability" pitch has collapsed — polls show DSA-backed Abdul El-Sayed running stronger against Republicans in Michigan than moderate Democrats.

Outlook: Expect more progressive primary upsets in Colorado, Minnesota, and beyond as the party's base keeps abandoning establishment candidates.
