Did Trump win anywhere in NYC that was not heavily Orthodox Jewish (like Midwood in Brooklyn that my Dad grew up in), or heavily Italian precincts?
Trump won in the more heavily Irish areas of the Rockaways, like Belle Harbor. He also won a precinct in the heavily Irish community of Woodlawn, the Bronx. Whitestone, Queens, which he largely won, has a bit of a mix of white ethnics and Asians, and is not necessarily Italian or Orthodox.
Trump did well in City Island, Throgs Neck, Bronx.
But he didn't win either community outright. He seems to have only won the Country Club section of the Bronx.
