First I am not exactly sure what stuff you are referring to. Second most us Jewish Democrats are not tremendously caught in identity politics (or at least as it relates to Jews, some are certainly caught up in other forms of identity politics) but rather use our background and upbringing to inform our politics on a whole range of issues. I wouldn't presume to speak for all Jews, but for many of us that leads us to a liberal perspective. Edit: Also we are about 2% of the population at most, I love that we are seen as having tremendous power, but in terms of votes, we don't have it.
Israel doesn't matter in the eyes of American Jews? Shocking.
