Murray Rothbard practically started the libertarian-to-fascist pipeline. Call him a pioneer on the trail, that became a pipeline, and is now a superhighway. That's how long this has been going on. He went from protesting the war with the hippies to teaming up with fascist Pat Buchanan.
Meanwhile, the Kochs took the gradualist approach. They still went from libertarian to fascist, though. LP to Tea Party to Trumpism, with their think tanks normalizing the ride, and giving the fashies better arguments.
