Because the crimes of the modern Israeli state are not an inherent aspect of being Jewish, and many Jews are skeptical of a party unconditionally defending it.
But Palestinian American voters trend Democratic, why would Jewish voters want to stay in a party that is heading towards a more pro-Palestinian bent?
There is a reason why the Jewish vote is for the taking for Republican candidates in the Northeast and so on.....
Jewish voters should be more Independent-minded, should be voting more Independent....
As has been said above plenty of Jews prioritize issues other then Israel but even among those who care about Israel there's many who are critical of how the Palestinians have been treated and would even welcome a Democratic Party that took a more even handed approach to the conflict.
