It's not a joke -- "populism" is a silly term that has no meaning whatsoever.

I have no idea why you cite the Electoral College here, as you seem to be arguing that the "popular" candidate should have been given the 2016 win.   

As we both know, the candidate who actually won the election did so within the terms of American civics and electoral law.   To say that "populism" was the reason, is to say nothing.
