Or Richard Nixon. Gave us the EPA.
Nixon was being driven leftward, I would argue, by a tsunami of Fabian Supreme Court decisions concocted by Fabian positivists on the Court and of liberal slime vomited out by media, academe, and furiously networking (conspiring, plotting) liberal legislators, opinionmongers, and jurists.
Think of the Sendai tsunami: black dirt, cars, buses, pieces of houses, human bodies, aboveground fuel tanks, 50-ton fishing boats. That was liberalism in the 60's, and behind it all, KGB Active Measures and the old COMINTERN, renamed in America the "New Left". (Examples: Tom Hayden, Bill Ayers, Bernardine Dohrn.)
