The interesting thing that gets ignored is that most democracies choose their chief executives indirectly. Westminster parliamentary democracies do it inherently. Those that do direct election tend to require a majority, with a runoff if nobody gets 50%+1. That means, among other things, that Hillary would not necessarily have "won" a popular vote in 2016. It would have been a runoff, with results ultimately depending on how the libertarians went.

One other interesting thing is that most of the better world leaders tend to have been elected indirectly, while many of the ones elected directly tend to be pretty despicable characters.
