I don't think the maps posted here tell any sort of story. Dirt doesn't vote, people do.
Forgive me if I don't get the explanation precisely right, but this shows the country weighted by population and which way the voters went. The majority of the country is reddish-purple, which is something north of 50% for repubs. But the big blue areas, probably 55-60%+ for D, control a bunch of electoral votes. That's a problem. But I'd like to see the electoral votes overlaid and maybe it looks more even.
Popular vote still has its problems, too. I don't think people should be ignored and their vote diminished for choosing to live in the 99%+ of the country without highrises.
An uninformed electorate is far and away the biggest problem. Would be nice if the 4th estate could properly educate voters, but they care about ratings now.
