Speaking as someone who's neither a citizen or resident of the US, but would no doubt will still be affected to some extent by the results of your elections.
Whether the electoral college system has more or less merit than a simple popular majority seems to be the least of your problems.
The founding fathers came up with a pretty good system, no doubt, but it seems to me to have a fundamental flaw in that it reaches an equilibrium with only two viable parties.
Does it seem reasonable that the opinions of 325 million people are divided into two nearly equal halves (to within less than a percentage point), votes for the smaller parties are functionally equivalent to liking someone's post on Facebook, and the party in power just flips over to the other one once people get bored with the one that's in the spotlight, or because the other party managed to spend a few more million on advertising and managed to get marginally better brand recognition?
Does it seem reasonable to sum up all your values and make a binary choice based on which side of the threshold you land on?
Well, the answer to those questions doesn't really matter, because you're fucked regardless, your political system has a fundamental flaw, and through the processes that turn a novel upstart concept into a baroque series of rituals observed out of habit, anyone who has any hypothetical power to change it is formed by it and reliant on it to keep their place and win their little victories within its framework.
