The sad truth is that Jews have always been used as a convenient scapegoat for grievances of all kinds, and this is just as true on the left as on the nationalist right. For example, Marx famously blamed the rise of bourgeois capitalism on the Jews, and this casual anti-Semitism was picked up by many on the left.

Your argument is intentionally mixing "is" with "was".
Marx died 140 years ago, and there are no ethno-nationalist voices of significance on the left today. In the US context, after the civil rights movement of the 20th century those people left the Democratic party as the parties realigned themselves.
Today it is largely a right wing phenomenon, carrying forward the tradition of right wing ethno-nationalism that persisted from the previous century.
