is true that they can perform this, but it is false that this is the
only strategy for the A-voters to prevent the C-voters from
manipulating the election by burying. In fact, it is far more natural
for the A-voters to just approve B which effectively protects B from
losing.<br><br>You could answer that this requires that some of the

That is one possibility, but another is that the A>>B>C voters
are simply unwilling to cast a "dishonest" vote. They have a
clear favorite, and a "lesser of two evils", and they want to cast a
vote that reflects precisely that set of preferences.<br>
