The resurgence of the term "populism" has always been curious to me. As far as I can tell it means "people not voting how they are supposed to". Much like how we have ousting/coup, freedom-fighter/terrorist, government/regime, we have democracy/populism.
For the majority of cases, it just means "ignore the complexity of reality and go with the simple solution". Sometimes, populists do really believe in what they are saying and doing. And the simplicity is what makes them popular - hence populism. The problem is that reality doesn't care. I have yet to see the case when following a populist leader doesn't end up in a disaster.
So everything is populist. Again which makes the term meaningless.
