[EM] Tentative replacement for CD

[Jameson Quinn]

Again, what you call ABE, I call chicken dilemma. And I believe that SODA
resolves it, especially with the optional rule for that
purpose<http://wiki.electorama.com/wiki/SODA#Finish_resolving_the_.22Chicken_Dilemma.22>.
But even with that optional rule, SODA does not meet your criterion; in
fact, it fails in at least two separate ways. (Candidates can truncate, and
it works in some cases unless the C candidate(s) help(s) resolve it; voters
can truncate, and it works, but is contrary to their laziness)

> "The A voters" are the voters to whom A is favorite.
> "The B voters" are the voters to whom B is favorite.

> "The others" are the candidates other than A and B.

> A voter votes sincerely iff s/he doesn't falsify a preference or

> Premise:
>
> The A voters and the B voters are, together, a majority.
>
> They all prefer A and B to the others.

> Voting is sincere, except that the B voters refuse to vote A over anyone.

> Requirement:

> Either A wins, or A and B win (tie), or neither A nor B wins.
