[EM] Irrelevant Ballots Independent Fallback Approval (IBIFA)

[Dave Ketchum]

Without the puzzle sentence all that get ranked get counted.  Fine  
with normal truncation, which  is normal for ranking.  If someone  
ranks the bottom those count as least liked and rarely, if ever, cause  
trouble.

With the sentence but no truncation, the bottom rank gets treated as  
Bottom.

With the sentence and truncation it is easy to think of the lowest  
actual rank as required to be treated as bottom.

Considering possible write-ins, do they make us see truncation?

I understand Chris is considering:
| I might change "ranking above at least one other candidate" to the  
simpler (and more traditional) "ranking in any position".
