Indeed, the vast majority of Trumpers at this point actually hold very bigoted, often straight antisemitic views.
But the complicating factor is the significant evangelical (really, white Christian nationalist) influence on the modern GOP, which views Israel as integral to their chances of experiencing “rapture” (and avoiding death), so actively work to support conflict in Israel in order to achieve elements of the biblical prophecies related to the Holy Land.
Most of those see Jewish people as “murders of Jesus” but, at the same time, the Jewish state as a “necessary evil”.
They are deeply twisted, malicious people when you really study their belief systems and actions, even ignoring their contradictory support of the conflict in Israel, Palestine, and the broader region.
