You vastly underestimate the judgement and intelligence of American Jews. Liberalism is an ideology of wisdom, compassion, and true American patriiotism. It is the position of enlightened people.Most US Jews are irretrievably liberal. US Jews have been in the forefront of the American Labour movement and the Civil Rights Movement since the 19th century. And, reciprocally, for decades the non-Jewish US Left took a stand (albeit avery tepid stand) against the institutional anti-semitism that was common in the US.
However, in recent decades, the US Left has abandoned its Jewish members to create a marriage of convenience with Islamic militants (and in the process turning its back on the principles of racial equality, religious tolerance and women's rights that defined it for most of the 20th century).
It is difficult for many US Jews to abandon what in many cases is a generational attachment to liberal causes and will turn a blind eye towards the current administrations mistakes, blunders, and occasionally malicious abuse of American liberty at home and American allies abroad.
On the plus side, more and more US Jews are embracing Libertarian and Conservative ideals and support of Israel is at an all time high among the American Jewish community.
In short, most Jews are smarter than you.
