As a side-note any exit poll of NE also needs to include Massachusetts Jews in places like Brookline/Newton who probably voted 85%+ for Obama in 2008. Even if McCain managed 37-40% overall of New York Jews(and 85-90% of Orthodox) he quite conceivably could have lost them about 80-20 outside of New York.
Heavily Jewish towns in Massachusetts/Connecticut were pretty heavy for Obama.
Brookline 82.3% for Obama
Newton 76.4% for Obama
It's not just NY state it's also in NJ
some Heavily Jewish areas in NJ went for McCain.
I see no proof that overall the non Orthodox, Russian vote outside of the NE is MORE liberal than in it.
keep in mind the bay area is in the west and was almost guaranteed to be Obama's best area amongst Jews in the country.
The McCain votes in those towns were not coming from the Jewish residents.
