Not Really Random

Inistead of "Margins Random Ranking Example", I should
have said "Margins insincere extension example".
Of course in example 4, the A voters extend their ranking
in a way that isn't random.
And of course, especially in a public election, if the
extension is genuinely random, it will cancel itself, as I said,
and it won't affect the Condorcet winner's win.
But it can when it's done lopsidedly, as in example 4, and,
as the example shows, it's a problem in Margins too. A bigger
problem, because it succeeds.
Votes-Against's truncation defense against order-reversal
(or insincere extension) is a general property of that method.
