Wonder who the Upper West/East sides vote for in a Clinton/Sanders matchup. Probably splits down age lines again. A lot of the old money/old jewish communities are more mainstream Hillary type people while Sanders could do well with the younger liberals in Manhattan.
Are white Manhattanites actually that left-wing, or are they mostly "social liberals"?
What's the ratio of business-oriented professionals to "creative class" professionals and educators in Manhattan? Brooklyn?
In Brooklyn, I presume that Blacks are the plurality of Democratic primary voters.
