Actually, they do.
I live in Mount Kisco, and there are dozens of working class towns like mine in Westchester - we do not all fit your caricature of rich snobs. (And what on earth could be "more urbanized" than Manhattan??) The illegal immigrant population strains social services to the breaking point and tremendously increases crime. Virtually everyone here is fed up - but stymied, since everything the law-abiding citizens have tried has been thwarted by the illegals' legal victories, ironic enough.
I was referring to the folks in Scarsdale, Pound Ridge and Chappaqua. The only folks from Westchester I meet who really give a sh-t about immigration are the usual suspects (blue collar white Catholics from North Yonkers, Dobbs Ferry, etc.), who are a minority in the county. Westchester has been blue for some time, with the limousine liberals who move up to the towns I initially mentioned from Manhattan after they decide to breed. They vote for the same liberal Dems as they did when they lived in the city. Immigration is not a major priority for them.
But since you live in a county where people vote for the likes of Nita Lowey and Eliot Engel (who was my former congressman, btw. A step up from his predecessor Mario Biaggi, but still a scumbag), you are SCREWED.
I never thought I'd say I'm afraid to go to MK, but I'm afraid to go to MK.
