@hightor,
You may be confusing the personalities of the politicians you cite with the policies they advocate. Laws and government regulations that unduly restrict individual freedom and choice are themselves the essence of authoritarian government. That these laws and regulations are the result of the advocacy of "progressives" who claim they know what's good for everyone else and design government managed programs to enforce them is itself a hallmark of the authoritarian character of their sponsors, even though, on a personal basis they might not be widely perceived to be authoritarians.
Conversely leaders with characters perceived to be authoritarian, who propose and enact laws that enhance individual freedom and reduce the intrusiveness of government into the lives of its citizens, are hardly authoritarian in any political sense.
