True, not all Jews are liberals, and I am glad you are not a liberal, but you do need to come to terms with the reality that the vast majority of them are. I also do not see why it is wrong or inappropriate to ask the question of why the vast majority of Jews are liberal.
Nothing wrong with probing the facts, but do you think Moses was a liberal? You think Joshua was a liberal? You think Samuel was a liberal? You think King David was a liberal?
I would propse that perhaps Kings Saul and Soloman were liberals and look where it got them.
I think I'm starting to notice some of the stereotypical NPR-listening jewish liberal hordes coming around. Some of my friends that had supported Gore, now support Bush and laugh at the thought of "what if Gore had won."
