There is a good possibility, that the 85% of Jewish voters who will return to vote for Obama (like a dog returns to its own vomit) are also not very strong supporters of the concept of Israel. Else why would they think they are “better off” in the US than they may be in Israel?
If they were in Germany in 1933, they probably thought Hitler would actually be a good thing, because he only wanted to get rid of the "Bad" Jews.
There weren't 85% of Jewish voters who voted for Obama in '08. The highest number I saw - and just about all of them were overestimates, when you consider who did the polling - was 78%. The guess here is that the REAL NUMBER was about 70%.
This year the guess is he won't top 60%. Remember that this heckling was from a subgroup of Jews which the 'Rats think they own, which is why they chose that particular synagogue to begin with.
