I have always been told that the higher population areas in NY are huge DEM areas!!!
Staten Island is still very conservative.
Brooklyn has changed greatly since the "hippsters" and "movie stars" and lefty elites took it over.
The Bronx is divided by various sections... some quite affluent.
Queens has changed GREATLY in the past 50 years, with a gigantic influx of Koreans and Chinese. I'm not sure about where this population now sits, vis-a-vis politics.
Manhattan still has pockets of Conservatives/CINOS/RINOS. Be that as it may, a LOT of DEM voters there, HATE Hillary.
Long Island and the rest of N.Y. state belong to Trump; at this moment.
