After 4 years you are still on this lol.Simple answer: It happened because of the stupid electoral college system. Bunker Boy "won" with 3 million FEWER votes than H. Clinton and he "won" because, sadly, there are many idiots who believe Trump's BS and other rightwing nonsense.
This has been the system in place, electing many other Presidents and will be again.
Again the “smart intellectuals“ are the only ones that know what they are doing, this is exactly why he won because the average working American is so fed up with these politically correct assholes that look down on the average “ deplorable” working American and Hilary was the hated champion of them and they were dumb enough to shove her continually in their face.
It seems this has still not quite sunk in yet.
