Zohran Mamdani, who vowed to have police arrest Benjamin Netanyahu if he visits New York City, leads among Jewish voters by 17 points in the race for New York City mayor.

Zohran Mamdani is indeed a prominent candidate in the 2025 New York City mayoral election and is noted for his progressive and democratic socialist positions. Multiple sources confirm that he leads or is favored in polls, including among Jewish voters, with one poll indicating he has the largest share of Jewish voter support at 37%, though the specific claim of a 17-point lead among Jewish voters is not explicitly confirmed in the sources provided.

Additionally, Mamdani has made controversial statements regarding Israel and Palestine, which have drawn attention and criticism. However, there is no direct, verifiable evidence in the provided sources that Mamdani has publicly vowed to have police arrest Benjamin Netanyahu if Netanyahu visits New York City. This part of the claim appears to be either an exaggeration or misinterpretation of Mamdani's stance on Israel-related issues.

Therefore, while Mamdani's lead among Jewish voters and his prominence in the mayoral race are supported, the specific vow about Netanyahu lacks clear evidence.
