I'm going to have to spend some time reading over your reference when I have the free time, since it looks quite interesting.
But I can already tell you by the complexity of what that article is trying to show that most people won't understand it and won't care.
When I vote, it's in part to declare what I want and what I believe in. I generally don't like Democrats and I don't like Republicans. If I want to vote for the Green Party candidate, then I want to vote for the Green Party candidate and make it known that that's who I want to win. I don't want to be stating that I equally approve of both the Green Party candidate and the Democratic candidate since that doesn't accurately represent my opinion.
Given that the Green Party candidate is not going to win, I generally vastly prefer the Democratic candidate to the Republican candidate, even if I don't like the Democratic candidate one bit.
I don't want to vote in a way in which my statement is that I equally prefer the Democratic candidate to Green Party candidate. I want to vote in a way that states, "I want the Green Party candidate to win. And if I can't have that, I'll reluctantly settle for the Democratic candidate over the Republican candidate."
Voting in a way in which one's desires are clearly indicated is what most people would want, I imagine, even if it has some counterintuitive results at times.
Also, at least on a cursory reading, it seems that the author of the article has a bias towards "moderate" candidates winning. Who says that I want a moderate candidate to win? I want some serious progressive change!
