Class warfare alongside corporatist favoritism was and remains the hallmark of the postmodern Left, and RINOs a plenty are of the same "party."
But looking back, this was the general playbook of the National Socialists, the Soviet Socialist, the Sino-Socialists and many smaller dictatorships, each at war against a middle class. The cycle repeats.
The Dems have just enough RINOs in the fold to point at and say, “See! They hate the middle class and give breaks to oppressive big business.”
The RINOs just shuffle along.
