I don't agree. I think this changes the issue and focuses on one specific
scenario. It's not the normal situation that one needs to truncate all one's
compromises strategically; if every candidate were always a target of burial
strategy, then a weak unknown candidate would win every time.
The usual scenario that gets posted here involves supporters of one of the
two major candidates (X) taking advantage of the fact that the supporters of
the other major candidate (Y) are expected to list X as a compromise choice.
Under MMPO, Y voters should not do that: They shouldn't list their only
serious competition as a compromise. Does that make LNHarm an "empty victory"?
I don't believe so.
