The mainstream non-Orthodox American Jewish population is
very Democratic. The national exit poll, for instance, had (all) Jews at 78% Obama, the aggregate of state exit polls (which, it's worth noting, is a different and larger sample than the national one) had Obama at 76%, and Jewish respondents to the Gallup daily tracking in October were 74% Obama (77% if you redistribute the undecideds - source for all these at
http://thesolomonproject.org/, the link under "headlines"). Meaning presumably that the not-all-that-religious were somewere in the 80's for Barack.
Does Pittsburgh have a lot of Italian areas? If so, the contrast between those and the NYC ones is perhaps more interesting, since I might guess (though I don't know at all) that they're more similar in non-political aspects.
