What is this obsession with states? They're arbitrary units of order meant to make managing populations easier. They don't magically imbue the people who happen to occupy that specific spot on the planet with magical abilities. People are able to express there peculiar needs through the popular vote just fine, if not better than in the EC. And again, what part of math do you not understand? What 10 states win you the popular vote, please tell me.
And low turn out? The U.S. is notorious for low turn out and one party's entire election strategy hinges on driving turn out down. The popular vote wouldn't force it lower, it might even drive it up (it probably just stays the same)
What allegations have I made without evidence? No ranking of democratic health from serious people has the U.S. at the top. High, sure, but definitely flawed and with room for improvement. The EC is one of its flaws, which again, the fact that no other country has ever tried it should be a glaring red flag. Democracies are enough alike that they share comment instruments and features throughout history. It's clearly broken, hence why it was amended within a decade of its creation.
Finally, again, you would need to focus on several more uban areas than there are battleground states right now to win a popular vote. Are done trying to pretend that the EC doesn't incentivize politicians to ignore more of the country than in a popular vote?
