I know a few Jewish folks. The majority of them are libs. They do not identify with Israel in any way. They have no loyality to Israel and very little religious tie if any to the Jewish Religion.
They will vote for Obam.
I have Jewish friends and family who are Obama supporters. That said, I don't think they have thought much about the true meaning of Obama's anti-Israel position and will soon have to confront that and all that means for their friends and relatives.
