As reported by the NY Times:
“Mr. Obama’s worst precincts were in Orthodox Jewish areas like Ocean Parkway and Williamsburg in Brooklyn and Kew Gardens Hills in Queens. In a few precincts in Borough Park, Brooklyn, Mr. Romney won more than 90 percent of the vote” (NY Times).
There was even one precinct in Gravesend Brooklyn, home to Sephardic Jews, where Romney won by an incredible 97%.
At the link above, there’s a map showing which areas of NYC went which way. You can see a swath of red in Brooklyn which represents the Jewish parts of Brooklyn.
But unfortunately, the “elite,” liberal Jews of the Upper West Side look like they went as strongly for Obama as the Jews of Brooklyn went for Romney.
