Does she observe kosher laws and not eat anything on Yom Kippur? I doubt it, but that wouldn't put her as much different from many Reform Jews who would claim to be religious. So no clue really.
I should note that the only Jewish politician who makes a big deal of the religious aspect of their Judaism is Lieberman. There was a bit of controversy when he broke his Sabbath to vote against the resolution condemning the surge, considering he has never broke the Sabbath before.
not concerned about what someone was or believed.
off topic: is she still Catholic? she doesn't seem like it to me
I think she went from being raised Catholic to non-religious to evangelical and then back to Catholic.
