I'm not sure whether the orthodox Jews really compensate for this nationwide effect. I'm also not sure how the hell to characterize the places they live on the urban/suburban scale...
Eh well his point is valid if you look at the parts of NYC he's talking about, but this is similar to someone in a Cuban part of Miami arguing that urban Hispanics aren't likely to be Democrats. He doesn't seem to realize that Jews outside of NYC exist (and by this we're even including the rest of New York State, since places like Monsey and Kiryas Joel are obviously not urban.)
And of course this all ignores the fact that the Orthodox are a very very small percentage of the national Jewish population if you disregard his No True Scotsman argument.
it's not just NY (maybe the "park" makes it rural)
Baltimore McCain won Park Heights.
Chicago McCain won West Rogers Park
you can also spot Orthodox presence on a Obama McCain map in Greater Miami, Greater Los Angeles, and Greater Cleveland.
Where in Greater Los Angeles?
Beverly Hills
Iranian Jews, correct? I didn't know they were orthodox? Probably supporting heavyhanded US military action and wealthy to boot. I can see why they might vote Republican. Of course there's a lot more Jews that live in the Greater Los Angeles area and they vote Democrat.
