He didn't win the popular vote, and that's a fact.
Of course Trump didn't win the popular vote. That is not the point of my argument and that was not the point of the election. The point of the election was to win the electoral vote, and that is what both sides' campaign strategy was based on.
Take California, for example. Clinton won by three million votes. But it doesn't matter whether she won by three million, ten million, or ten votes. It was a foregone conclusion that Clinton would win California, so Trump spent little effort campaigning there. If the contest had been for the popular vote, Trump would have campaigned in the largest population centers -- like California -- and presumably he would have gained more votes there. I suspect many Republicans didn't even vote in heavily blue states, because their vote didn't matter anyway.
The whole point of the campaign was to win the electoral vote. You can't say "Well, Hillary won the popular vote, so she is the real winner, and it is only a statistical fluke that Trump won." The goal was to win the electoral vote. If the goal was to win the popular vote, it would have been a different campaign and a different election and Trump may have won that also.
