I agree that President Trump won the election because of the antiquated Constitutional provisions governing presidential elections. I do not regard him as fit for office and find his behavior demeaning to the majority of the American public that did not vote for him.
I see this statement over and over again, and it shows the gross misunderstanding and lack of knowledge of civics and the history of pure democracies by those who say it.
First, the electoral college is not antiquated. According to Google, antiquated means old-fashion or outdated. Well, the Electrical College has been around only for the age of the USA; pure democracies, which is what you are advocating for, have been around for eons. The Electoral College is not old-fashion in comparison; it's the opposite.
Second, pure democracies don't work by the tyranny of the majority. Having a pure democracy allows the majority to only consider what is best for them, eventually causing dissidents amongst the minority. Read the Federalist Papers by James Madison for an argument against pure democracies with no checks on power that is more eloquent that what I can muster here.
There are examples of this playing out through history that has indirectly led to the downfall of governments.
Third, the Electoral College forces our presidential confidantes to pay attention to the entire country, which I see as a plus. I don't know how you can't. If presidential candidates ignore enough states, like the three in the Rust Belt, then they looses. If a party ignores a state, it becomes a swing state and demands that that party start paying attention to it again or that state switches sides. Such was the case in CA; CA was a strong republican state prior to 50 years ago. FL has only recently become a swing state. WV, which is why George Bush actually won (not due to FL) was ignored completely by Gore, since he knew for sure WV would vote blue, just like Hillary knew for sure PA, WI, and MI would for vote blue too.
"It ain't what you don't know that gets you in trouble, it's what you know for sure that just ain't so." Mark Twain
Last, as the quote above implies, it prevents complacency and arrogance. What if, according to Colin Powell, Hillary did not "ruin everything with her own hubris" and actually paid attention to the Rust Belt? A lesson I am sure our next candidates in fours years won't forget.
I consider the Electoral College, regardless if my candidate wins or looses, an ingenious way to avoid to the pit falls of pure democracies and another great example of the many checks and balances our government has.
