Sure. If I create a district that gives 80% of its vote to your candidate, and four surrounding districts that give my candidate 55% of the vote, then I win 4 to 1. That won't work. Tinker with the Electoral College and it's likely to be scrapped entirely.
The article writers idea seems to be to have state legislators choose the electors. That won't happen either. He's under a lot of illusions about the character of state legislators. Why would they all of a sudden step up and become infinitely wise and courageous philosopher kings entitled to chose our leaders for us?
