Gramsci indeed is a good choice, the Frankfurt School, Saul Alinsky. Personalize, ostracize, frame, shame, and demagogue. No compromises, no surrenders, no parlays. No letting up or letting go. No negotiations - present a list of demands, agitate until they are fulfilled, then, once they are, declare them to be "not enough."
The left instinctually understands this, to their credit[?] Few members of the "right" do, only Lee Atwater clearly did and beyond him Nixon, Pat Buchanan and Joe McCarthy half-understood it. Among classical liberals, the choices are even more bleak, you'd pretty much have to go back to Andrew Jackson or John Hancock in the US.
You forget the Tea Party.
