I have my doubts. There is no way Dems have only a +8 advantage among Jews.
This is a standard small sample outlier.
We have no idea how many of the 812 respondents were jews, only the percent by religion with preferences.
My guess would be that there were between 20 and 40 in the whole sample. Can’t say much about it.
Anecdotally, I know some American-born chabad that will vote for Romney because they are disappointed with the empty chair.
