Winning the popular vote means getting more votes than any other candidate. Hillary won the popular vote. Most people understand the concept of the Electoral College. Let it go...no need to be defensive about the election.
I’m not convinced that “winning the popular vote” means what you say. Maybe it does, I’ll look into it.
I’m also not convinced “most people’ understand the electoral college system.
In any case my concern is not about the election but about the media (and others) spreading information which is not true or which is misleading. If they say Clinton got more votes than Trump that is true. If they say she the popular vote, I think that is misleading, since a majority of people voted for someone other than Clinton.
