I want to profoundly apologize for Donald Trump.
Don't sweat it. I watched his victory speech, and he sounded more presidential then than at any point in his campaign, so maybe there's a chance that President Trump is better than many of us fear.
I blame the voting system, people cast their votes to try to get the best outcome they can within the confines of the system, and noone can blame them for that. I do exactly the same thing when I vote.
Our election systems are flawed, the Electoral College perhaps a little, the FPTP system extremely so. Until we get a system that represents the voters more fairly we are doomed to be stuck with a 2 party system where the winning party represents a minority of the people it represents.
If Trump does no other good, perhaps his election will point to how flawed our elections are and how much they could be improved.
ETA: You might well be wondering why a non US person is so interested in the US voting system. It's because what America does tends to follow on in other countries later. (which is also why California voting to legalise recreational use of weed is such a good thing, but I digress)
If the US scrapped the FPTP voting system and replaced it with a proportional representation system like STV then it would be a lot more likely that in the UK we would do a similar thing, which can't come soon enough imo.
