Your table doen't come out in my browser. The Wikipedia comparison page
justifies the belief that election science has followed economics as the
dismal science. Where wealth and power are concerned, thought flounders.
It is not just that a classification is less potent than a
transformation, which is to say, for example, that Linnaeus preceded
Darwin. The elections classification itself is incoherent, being based
on arbitrary criteria, rather than the necessary attributes of all
elections and their extent of development.
