Maybe buy this.
Trump defenders, or D haters, or whatever it is that you are, love to point to how big Trump's victory was—dominant and all, dismissing the popular vote thing along the way.
Michigan, Wisconsin, Pennsylvania and Florida were all vital in building Trump's coalition of states, giving him 75 electoral college votes towards his eventual total of 306. Had Clinton won these states, she would have been elected as the next US president.
In these four states, all of which voted for Obama in 2012, some 23 million people voted in total. Trump won these states, and thus the election, by a combined margin of just 227,000 - one per cent of the electorate.
Two of those four states make the very, very short list of states found to have been the most successful at executing on voter suppression strategies, strategies targeting voters who tend to vote Democrat.
I know you know this, though, at least via a general awareness, because you're constant reminding people that Trump won is an attempt to solidify it in your mind as a win, because it bothers you that he kind of won and lost at the same time.
If the shoe was on the other foot, if Clinton had won the EC and Trump the popular vote, it surely would have bothered Clintonites the same way.
