I would disagree that that EC is working, but its failures are certainly not the reason Hillary lost. She was absolutely the worst candidate in modern political history, and that's honestly the only reasonable conclusion one could come to after losing to the most unpopular candidate in modern political history.
More important than the narrow EC issue is congressional apportionment. The last time there was an increase in congressional representation was in 1913 when there was approximately 1 representative to every 200,000 people. Apportionment used to go up steadily with population increases even when a representative's constituency was only increasing by 10 to 25%. We now have 700,000 people per representative. No matter how conservative you are, it's absurd to argue that this is what the founders had in mind. Not only has the voting power of a rural American increased exponentially, but we have a situation in Congress wherein small groups of reps can obstruct legislation that is nationally popular and that would pass if the apportionment ratio was even 1 to 400k. The current situation is unfair and it's certainly not a working representative democracy.

Now there's something we can agree on. What I THINK isn't appreciated by many folks who lean to the left is that MANY of us who voted for Donald Trump have been totally disenfranchised with both Democrat AND Republican parties. I also think we can agree that Hilary was for sure the favorite of the DMC (look at how badly the DMC turned on Bernie). THUS, Hilary was the ESTABLISHMENT champion.
Indeed, many of us believe strongly that she wasn't only the establishment Democrat favorite, but the establishment as a whole. I'll admit that the RNC did FINALLY get behind Trump (sort of), they did it very reluctantly and without full force. One must ask themselves why??
The standard answer which most people want to make is that "he was just such an obvious buffoon". But, many of us looked differently upon the situation (this is important so hear me out). For many of us, we've been just as dissatisfied with the status quo in this country as many on the left have been. We've seen the same injustices, although with perhaps a right leaning viewpoint but nonetheless, we see what's happening. Hilary represented the status quo, as would have someone like Jeb Bush, or even Marco Rubio. These are all establishment people. John McCain? Linsday Graham? Totally owned by private interests. Beyond corrupt.
Many of us believe, also, that there doesn't exist many major, hard hitting, differences at the level of the status quo. Like, by definition. And the status quo Republicans and Democrats have, in many of our opinion, been projecting a false Red/Blue paradigm where we all fight over social issues which the true monied interests view as collateral damage, not likely to effect their power, wealth, and influence in the U.S. So, one camp suggests they care more for the poor and minorities, the other camp pretends they want to lower taxes for the poor and protect the life of a fetus. Now, I'm not saying these aren't important issues. Indeed they are very emotional ones. But, they are also divisive. But, at the large policy level. How do we deal with a large, inflated banking system. How do we conduct ourselves in foreign interventions. What will be the status of the corporate and executive elites. This never really changes.
Meantime, the "people" are busy arguing whether we are simply damaging our environment via pollutions, and what constitutes climate control versus global warming, and we get all wrapped up in these things which mostly (to sane people) comes down to semantics and where a little of both is probably happening where we are going through a warming cycle at the same time as the globe is also at all time emissions highs. Semantics, though, mostly.
Meantime, Americans keep battling it out on issues that are admittedly contentious, but that matter little to the elite. This is an opinion of mine and many others.
Many of us can agree that our country has been heading in the wrong direction on many fronts. The SYSTEM (including most mainstream news media) are a part of that SYSTEM. So are most Senators. Lobbyists. Defense contractors. Multinational corporations who's revenues often far exceed those of small countries.
That system is one which will fight for it's survival. It will fight very hard in my opinion. Collateral damage like gay rights/marriage and abortion completely take the back seat. What those interests care MOST about is that the system they benefit from does not change.
Hence, a rejection of both Republican and Democrat establishment figure heads, as the public (on both sides of the isle) becomes more wise to the old tricks of divide and conquer.
