Jonathan Chait:

The paranoid mendacity of Joe McCarthy, the racial pandering of Barry Goldwater, Richard Nixon, and George Bush, the jingoism and anti-intellectualism of Ronald Reagan, George W. Bush, and Sarah Palin---all these forces have embodied the essence of American conservative politics as it is actually practiced (rather than as conservative intellectuals like to imagine it). Trump has finally turned that which was always there against itself.
