[EM] voting system design puzzle

[Forest W Simmons]

MCA satisfies both conditions (clone free and avoidance of favorite 
betrayal).  It does use range style ballots, but it elects the 
candidate with the greatest median rating. If there are several 
candidates tied for greatest median rating, it elects the one with the 
greatest number of ballots that rate it at that level or above.

ER Bucklin (whole) based on ordinal ballots (with equal ranking 
allowed) also satisfies both conditions.
