The non-religious Jews, the lost ones, unfortunately did not receive proper religious training at home. They are the grandchildren of immigrants with Bundist ties in the old country, where being an observant Jew was a crime and Communism became the religion of all. This was all they knew; they had been robbed of their rich religious and cultural heritage. When they came to America in the early 1900s, it was a hostile environment for being a religious Jew. People were obligated to work on the Sabbath and holidays or risk being fired. Kosher food was not readily available and it was expensive. Religious practices, even if they had been brought over from Europe, took a second deadly hit. And so, the grandchildren and great-grandchildren of these immigrants barely know what it really is to be a Jew or the extraordinary significance that Israel has for us. What you don't know has no value for you.
On the other hand, the Orthodox Jews are very conservative in their outlook. They often decide on a candidate based at least partially on "Is he/she good for Israel?" So you cannot, with any validity, lump all American Jews together and call them liberals. I just hope that some day the areligious Jews will somehow come back to their roots and take up appropriate values, that they will heed the call of G-d when He promised to gather His chosen from their exile (including a SPRIRITUAL exile such as we have in America).
So you cannot, with any validity, lump all American Jews together and call them liberals. And I realize that and thus the reason for my post #7.
That notwithstanding, the PERCENTAGE of liberal Jews in this country voting for Democrats is appalling and does not reflect an abundance of overall conservatism in my opinion. Percentages and media coverage are what rules in today's world, and, collectively, Jews in this country are tagged with "liberal" without question.
