Benchmark Politics made a map for the Democratic primary.
Some comments:
No way does Rockland (that little triangle bordering Jersey and above NYC) go for Sanders. Not after his comments about 10,000 Gazans being recklessly killed by Israel. Rockland is the most heavily Jewish county in the country and ironically Jewish precincts are going to Hillary by 2-1 (which is what we saw in Mass).
Manhattan at the very worst leans Clinton, and is probably likely Clinton. Yes there are some young voters there but it is almost a majority-minority borough (only 50.7% white).
The Staten Island vote in Democratic primaries is much more minority than Benchmark is predicting. Very polarized area.
Putnam is not going to be strong Sanders; it is a swing county. Lots of actual Wall Streeters live there.
Orange (my old home county) will be a swing county. Definitely not strong Clinton
Sullivan went for Teachout heavily in the NY Gov primary so it's possible Sanders does well there, same as Dutchess. Lots of white hardcore progressives in Dutchess who fled from the city (a Sanders demo).
Columbia County is Sanders territory, as is Greene and Delaware Counties. Broome will be close because it depends on how many Binghamton University students vote there as opposed to Long Island.
Aside from Albany County most of the northlands counties are for Sanders or swing counties (those north of Albany).
Onondaga County (Syracuse) is lean Clinton, not lean Sanders. Monroe County (Rochester) is lean Clinton, not strong Clinton
