Sorry, if I didn't make the distinction clear. I am talking about the 
Condorcet (binary) count, not being an ordinal count, not the Condorcet 
preference vote, which of course is an ordinal vote.

"Hare RCV" is no less wrong for being repeated! I do not dispute that 
RCV loses information. Binomial STV is a remedy of this, and to a lesser 
extent traditiopnal STV..

It is Thomas Hare who is credited with the idea of the Single Transferrable Vote and that is the key innovation that was used to convince policy makers that were was no multiplication of votes and made the method feasible.

The author's define "an electoral system called true majority rule (or simple majority rule), in which voters submit rankings of all the candidates and the winner is the one who beats each opponent in head-to-head competition based on these rankings."
