Personally I don't think Trump himself is anti-Semitic. His favorite child married a Jewish man and now she and some of his grandchildren are Jewish. And he grew up in NYC where its hard to be anti-Semitic honestly. As a Russian-Jewish person growing up in NYC, I never felt or saw any anti-Semitism from anyone.

Still, all that being said, Trump is a Trumpist and he will use anti-Semitic images if it furthers his own ends. He only believes in himself. So whether accidental Antisemitism or real Antisemitism, it amounts to the same thing. A dog whistle for some of his supporters.
