Seriously, why are (most) Jews liberal? I just can't figure it out...makes no sense.
Large numbers of Eastern European Ashkenazi Jews were seduced by Communism because it was the enemy of the Czarist Russia under which they had suffered for so long. You won't find the same infatuation with Communism among Sephardic Jews.
They followed the philosophy of, "The enemy of my enemy is my friend."
Unfortunately, this love affair with Communism was brought to America by late 19th Century and early 20th Century Jewish immigrants before they had a chance to see for themselves what a horror Communism was. Throughout the 20th Century, the children and grandchildren of many of these early Ashkenazi Jewish immigrants were raised as "Red Diaper Babies" without questioning whether Grandpa's love of Bolshevism in the 1910's was justified.
The "Red Diaper" Jewish generations are now dying off from old age. The new Ashkenazi Jewish generations are seeing for themselves that the Left has embraced the new enemies of America which also happen to be the enemies of the Jews.
Following the "The enemy of my enemy is my friend" phenomenon, I see the younger Jewish generations leaving Grandpa's Bolshevism behind and coming over the to Republican Party.
At a really deep level I wonder if the Old Testament's messages are more black and white or 'structured' so that their ability to do simple analysis of the train wreck that liberalism has become impaired. Also, there is the history of subjugation that probably leads to identification with victimhood. If only they could look around and see the tremendous success that democracy (old liberalism) has given them.
That Jewish people can consider themselves Jews when they have no real affiliation with the religion of their heritage needs to be included in the analysis.
Tradition.
Most Jews vote for the democrats because they have a great sense of loyalty to FDR for stopping Hitler and the gang. They tend to be disconnected from day to day politics (as are most Americans) and haven't noticed how far left the Rats have gone. Just like with your average middle American Rat voter, if the media told the truth instead of shilling for the Rats, the Jews would vote Republican.
