One faction (that is, one arbitrary partition of the voters) can only control what 
it does itself. You're saying that the 17% faction doesn't have favorite betrayal 
incentive, because a different faction should have voted differently.

When I say "incentive" I only mean the opportunity; I don't mean to imply that
voters would necessarily be aware of, or inclined to think of, this opportunity.
