A recent Siena College poll conducted from August 1 to 7, 2025, shows New York Governor Kathy Hochul leading with 45% support against Republican challenger Elise Stefanik, who holds 31%. Hochul’s approval rating has improved to 53% favorable versus 42% unfavorable, up from 44% favorable and 48% unfavorable in February. In the Democratic primary, Hochul leads with 50% compared to 15% for Antonio Delgado. Meanwhile, Senator Kirsten Gillibrand’s statewide favorability rating has declined to 36% favorable and 38% unfavorable among likely 2024 voters, with a plurality of Democrats viewing her favorably but Republicans and independents viewing her unfavorably. In New York City’s mayoral race, Democratic socialist Zohran Mamdani leads with 44% support, significantly ahead of former Governor Andrew Cuomo at 25%, Curtis Sliwa at 12%, and incumbent Mayor Eric Adams at 7%. Mamdani’s net favorability stands at +14%, while Cuomo and Adams have net favorabilities of -17% and -28%, respectively. Mamdani’s lead over Cuomo has grown to 19 points according to multiple Siena polls. Younger voters under 35 and a plurality of voters aged 35 to 54 support Mamdani, although 75% of NYC’s Jewish voters view him unfavorably. Betting markets on Polymarket indicate Mamdani has an 82% chance of winning the mayoral election, the highest probability recorded, while Cuomo and Adams have 9% and 7% chances, respectively. This surge positions Mamdani as a dominant candidate in the upcoming New York City mayoral race.
