Jews who are serious about a traditional idea of God tend also to give the nod to traditional Christian conservative politicians. (The difference is not so much in general values as in theology.)
However most American Jews are not serious about this. Wanting to forge their own path, they fall on their knees to the Baals and call it freedom.
There is a vast difference between Israeli Jews and American Jews. Most American Jews are 3rd or 4th generation Jews that came from the holocost in Europe. They have no idea where their roots came from. They are more interested in in themselves, and not the problem that Israeli Jews have to face every day. As it was before WW2 Germany. Out of the 6 million Jews that were killed in Hitlers concentration camps, the majority were not German Jews. They were Jews from all over Europe. There were a lot of German Jews that voted for Hitler, in spite of people telling them of the danger Hitler was going to cause.
