Interesting Pew polling of Jewish Americans.

Large differences by age and party affiliation.

I should note they excluded Jewish Americans that identify as culturally or ethnically Jewish, but not by religion, unlike their previous polls. That's a rather significant change given there are a lot of secular Jewish Americans and they tend to be fairly liberal as a group, even relative to other Jewish Americans.
