For most American Jews, the core of their Jewish identity isn’t solidarity with Israel; it’s rejection of Christianity.
When are you idiots going to learn that the world does not revolve around your religion? The core of the jewish identity isn't solidarity with israel, nor does it have anything whatsoever to do with christianity. There core of jewish identity is, and has always been the jewish community. How could the core of their identity be rejection of christianity when judaism predates christianity by a couple thousand years?
This observation may help to explain the otherwise puzzling political preferences of the Jewish community explored in Norman Podhoretz’s book.
Neither Norman Podhoretz, nor anyone else has either the ability, or the right to dictate what someone else's political or ideological opinions are.
Jewish voters don’t embrace candidates based on their support for the state of Israel
Some do, but most likely tend vote for the candidate that they think will do the best job, just like the majority of voters.
as much as they passionately oppose candidates based on their identification with Christianity
If that were the case then there would almost certainly be no jewish votes cast in any election. Mostly owing to the fact that there are hardly any politicians in the US that don't go out of their way to hype themselves as belonging to whatever kind of christianity that will score them the most votes. And even with all these displays of blatant and outright christianity, jews still turn out to vote in large numbers during elections.
