Why are Jews predominantly liberal?

One of the most annoying voices on conservative talk radio is Mark Levin, author of the bestselling Liberty and Tyranny: A Conservative Manifesto.  However, it's all I've got some days, and once in a while, he has an interesting guest rather than the lowbrow callers that frequent the more rant-ridden types of shows. 

Today, he had Norman Podhoretz, author of the controversial new book Why Are Jews Liberals?

You can listen to the 10 minute interview I've excerpted from the Levin archive. But the main interesting points I got from the interview were:

1. In the mid 19th century, it was liberalism that defended Judaism from the threats of fascism.
2. In 1967, a great shift occurred in American politics.  The left became increasingly anti-Zionist to the point of being anti-Semitic, while the right, esp. the Christian right, began seriously taking up the cause of Israel.
3. However, Jews did not become conservative because

(a) Converting or turning to conservatism in Jewish culture is as objectionable as converting to Christianity, and most Jews abhor both.

(b) Liberalism has replaced the values of the Torah for most Jews - where the two disagree, most Jews now side with liberalism and NOT the Torah.  That is, liberalism is now the predominant religious stance of most Jews.

There's much more great content in the interview, including Jews' support for Obama.  Enjoy.
