Trump’s one book is a collection of Hitler’s speeches. It was a surprise he didn’t use it in lieu of a bible at his inauguration. Between that, his campaign against the Central Park five, his birtherism, his chintzy escalator speech, good people on both sides, and bad people on both sides remarks - just to start - an ideology emerges as a consistent driving force dating back more than 40 years.
The fact that a Jewish boy is boning his love interest and the star of all his wet dreams and occasionally getting her pregnant to boot is likely making trump more anti Semitic than less so, especially since this Jewish boy hasn’t solved Middle East peace or, reformed the government, or delivered on anything else he was tasked with and its making the old man look bad.

Self loathing and projection doesn’t require a specific target, just an available target.
