After doing my homework I've concluded that Johnson couldn't really be considered a -moderate-, which I apologize for.
Relevant:
I would suppose that the American center in comparison to the rest of the world would be about where I placed Gerald Ford, and the entire American spectrum would probably be a 16th of the size of this political compass to account for the wide range of political thought outside of the U.S. Obviously, assuming you're somewhat sane, Franklin D. Roosevelt definitely wasn't a communist.
That chart is really inaccurate. I don't know even where to begin, except to say that the entire authoritarian/libertarian scale there doesn't make any sense. Also, Reagan being to the left of GHWB, while Nixon is so far to the right of Clinton?
