The Satmars are not a pleasant people. That is all.
Why is that?
Even better example of the Satmar split - the town of Ramapo, Rockland County, New York. Bush's election district performances ranged from 10.6% (district 6) to 99.1% (district 57). A little something for everyone (although if you're a gentile Republican, you're probably screwed).
Alcon, it may be hard for you to know a lot about Ramapo, but being the town my dad grew up in and my grandparent's currently live I can provide some insight into why this happens. Ramapo is a large town broken into smaller villages. Some of these villages like the one my grandparent's live is Airmont, a fairly conservative area made of mostly caucausian christians. It also includes Hillburn, where my aunt lives, another conservative area. But, it also includes Monsey which is the Mecca of Jews in the northeast. People in Airmont despise the people in Monsey, and therefore there are great differences among the areas of this one town and I have no trouble believing the numbers you put forth.
