Overview
- Fresh September polling from Marist, Siena, Emerson, Quinnipiac and YouGov/CBS shows Mamdani ahead in a four‑candidate field, with recent toplines around 43–46% for Mamdani to roughly mid‑20s for Cuomo and mid‑teens for Curtis Sliwa, while Eric Adams lags in single digits to low teens.
- In simulated one‑on‑one matchups, the race tightens markedly, including Siena’s 48%–44% and Emerson’s 47%–40% for Mamdani over Cuomo, with Marist showing 49%–39% in a direct pairing.
- Pollsters note that if Adams were to exit, vote shifts tend to benefit Cuomo more than Mamdani, narrowing the race in three‑candidate scenarios such as Quinnipiac’s 46% Mamdani, 30% Cuomo and 17% Sliwa.
- Age remains a defining fault line, with Emerson reporting a 29‑point Mamdani advantage among voters under 50, and Quinnipiac finding Mamdani’s backers report the highest enthusiasm levels at 91%.
- Issue priorities diverge across coalitions, as Mamdani supporters emphasize cost of living while backers of Cuomo, Sliwa and Adams cite crime, and a Marist measure finds most voters expect Mamdani to win.
