I agree, the American Jews have been a very dependable Democrat vote for years. But, part of that is because the US has always be a reliable ally of Israel. Whichever party has held the White House, there have been enough Republicans and pro-Israel Democrats that Israel could always count on our support. Until 2008, when the Dems got a large majority in Congress and we have a guy in the White House who is clearly an Islamic sympathizer who has demonstrated a desire to please the Islamic world, which is inconsistent with being an ally of israel. I hope this is enough to force the American Jews to realize that the “New Liberal Democrat Progressive” sees the Islamic world as worthy of sucking up to for various reasons. And now that Iran will have nukes in about a week or so, this could be a major problem.
I do not think the support of Israel issue holds the pull it used to for the American Jewish community. At least not enough for them to overcome their naturally ingrained politically liberal impulses. I think this is particularly true for younger Jewish people who do not have the same affinity with Israel as the older generations did.The Israel issue is important to the Orthodox Jewish community but they are very small in numbers here compared to the Reform Jewish community. At best a strong Republican stance in support of Israel may sway a few Jewish votes but overwhelmingly the Jewish vote will still remain with the Democrats.
