I definitely would like to see it improved, I think the two party system sucks, and our voting system guarantees it, and the fact that my vote doesn't count for much because I live in a blue state annoys me a bit.
But the people did, in fact, select Donald Trump to be President. A penalty, that at times, is exactly what our society deserves. :/
As far as I can tell from Wikipedia, only five elections have ever been won by someone lacking a plurality of the popular vote. Three of those cases happened before 1900. If we look only at the more modern examples, the Republicans have won the presidency but lost the popular vote twice (2016 and 2000) and the Democrats have never done this. In fact, this is a true statement over all of time, but once you get back more then a century the political parties are so different as to make the comparison meaningless.
That is to say: the Democrats have never had a presidential election that they won without winning the popular vote. I do not love the two party system either, but in this case it doesn't feel fair to say that both parties are currently equally benefitting from the Electoral College.
He did, however, win the popular vote in both the 1860 and 1864 general elections (39.8% to the runner up at 29.5% and 55%, respectively) [1].
