I actually meant populist, meaning affiliated with populist ("of the ordinary people") political parties on both right and left.
Do all the non politically affiliated people who hate billionaires not count? Or why is the granularity here important? Your point is stronger the other way!
Meaning is derived from real usage, not from dictionaries. Descriptivism has won. And in the real world, it's simply used as a cheap shot to claim that certain policies or thoughts are only for the winning of votes rather than well thought out or other "ideology" based.
