[EM] Mutual Majority Top (MMT)

[MIKE OSSIPOFF]

Mutual Majority Top (MMT):

For any set of candidates whom the same majority of voters vote over everyone else,
the winner must come from that set of candidates.

>From such a set, or, lacking one, from the entire candidate set,
the winner is the most top-rated candidate.

[end of MMT definition]

MMT differs from MDDTR because the B voters in the ABE are forced to
admit that A is better than C, so that the method avoids a Plurality Criterion
violation if it elects A.

MMT loses the Mono-Add-Plump compliance of TTPDTR,
but thereby gains some simplicity.

It would be better to meet Mono-Add-Plump, if TTPDTR is accepted in spite of its
greater complexity. For the best methods, not as simple to define, it would be
necessary to have time to talk to people, and speak first about the desired
properties, and then about what it takes to achieve them.

I don't know if I'll get any other chances to get to a computer during today 
and tomorrow.

MMT meets 3P, but fails 1CM, as it must, since it doens't recognize one-sided
coalitions. It trades TTPDTR's Mono-Add-Plump compliance for greater simplicity.

It probably meets FBC.
