The Republican candidate running for New York City mayor in the 2025 election is Curtis Sliwa. He is a Republican activist and the founder of the Guardian Angels. Sliwa was also the Republican nominee in the previous 2021 mayoral election, which he lost to Eric Adams. Despite facing pressure to drop out of the race, Sliwa has refused to do so and is actively campaigning this time around. He is running on issues such as crime, people leaving the city, and the city's sheltering and care of migrants. Currently, the mayoral race also includes incumbent Mayor Eric Adams running as an independent, Democratic nominee Zohran Mamdani, and independent former governor Andrew Cuomo. This sets up a complex and competitive election for New York City's next mayor.
