@blatham,
Are you aware that Trumps' daughter is married to an observant Jewish gentleman? Your repertoire of slanderous and deceitful phrases from the Democrat group values textbook notwithstanding, the evidence strongly suggests that Trump's actions and decisions as president , have been very supportive of Israel and many Jewish values ( and also very opposed to Russian aims in the world). There is no real reason out there to believe he is, or ever was, and anti Semite - though your superficial recitation claims otherwise.
Many American Jews are of a very liberal political bent and, as you indicated, have long been strong supporters of the Democrat Party. I suspect that many will continue that support, in spite of the starkly anti Semitic and anti Israel rhetoric coming from both the prominent new young loonies in the Democrat delegation, and a growing number of others in the liberal establishment, precisely because Israel is not their only political concern. However, some others (I don't claim to know how many) will likely be put off by this growing anti Israel orientation among liberals across the country and see the elements of anti Semitism that are indeed present in it.
