Being a Neo-Con Zionist young Reform Jewish Republican I think I understand. Most Jews in this country are Reform, meaning that their religion aligns with their politics. Being very non-religious I am sort of unusual. If you look at the old Communist/Socialist revolutionaries(The Rosenbergs, Trotsky, David Horowitz and what he used to be and his parents) you will find plenty of Jews because that used to be the intellectual spring. Howard Zinn and Chomsky are Jews also, yet if you look at the semi-Jewish Karl Marx you will find an economic theory similar to the Quarter Jewish Hitler and the Jewish Chomsky, meaning in fact that there is a self-destructive mechanism within much of my religion.
Here are reasons why Jews vote Democrat usually and why they voted in 2006
1. Most Jews are Liberals
2. Fear of Christians(I know two people who voted Democrat in 2004 because of that irrational fear)
3. That it wasn't national
4. Because even Jewish Dems love Israel
5. The stereotype that Jews have "compassion" which is why there are so many Jewish Defense or Protection of enemy lawyers
6. Early American discrimination
7. Being one of the smallest minorities in America
8. FDR and his WWII fight into
(what also is interesting is not only did many of the first Labor Unions exclude Jews but also that Jews are even more loyal to Democrats than blacks, the most a Republican got in an election from the Jewish people is 50% which was Eisenhower, a time when the NYT and the WP endorsed him)
9. Robert Kennedy and Harry Truman and the old Democrat
10. The stereotype that Jews are rich(my theory is that the more one person has, the more Liberal they become)
11. Also that many Jews went into the Arts and want to provoke iconoclasticism within societies, now that second thing isn't Liberal by default but it sort of shows a mere likeness to the Alt. conventions of Liberalism.
I can also tell you, in many reasons, why Liberals hate Jews
Personally I think that even if they are the minority probably most beneficial to the GOP, they will still walk in a lockstep brainwash like so many other minority groups, Liberalism clinging from the veins.
I know that my grandparents on both sides were or are all Republican, my grandmother and grandfather used to be Democrats, on my dad's side, during the 60s until all hell broke loose. My father used to be a Democrat until he believed in an intellectual dishonesty and now is a Neo-Isolationist Libertarian Republican, whereas my mom is a Neo-Conservative Moderate yet very loyal Republican and while my mom is against guns(one of the reasons, possibly, why Jews can be so Liberal) she is for National Defense and is a diehard partisan on Iraq, my dad is the opposite. Personally for me it is slightly about Israel but it is also the envy and the rabid Anti-Semitism in the Left.
