"Leftist" by American standards in 2017 is, again, not leftist by world standards or even US standards in 1970-1990, except on a few social issues (e.g. Gay rights) or things that aren't even political in other countries (basic science). Bear in mind that Nixon tried to pass Obamacare and set up the EPA. Teddy Roosevelt set up the national park system.

Yes, if your standard for leftism is Joseph Stalin's Soviet Russia.
But that's like saying, "The right by American standards isn't actually on the right according to world standards, where the right wing == Benito Mussolini's Fascist Italy."
