[EM] lotteries

[Forest Simmons]

Here's an idea to stimulate thought:

Ballots are Cardinal Ratings or Ordinal Rankings.  Approval cutoffs are 
optional.  Some default scheme is used for ballots that do not have 
indicated approval cutoffs.

If there is a CW, the winner is chosen by random ballot among all of the 
candidates that have at least as much approval as the CW.

If there is no CW, the winner is chosen by random ballot among all 
candidates that have at least as much approval as any of the Smith set 
candidates, i.e. if there is a Smith set candidate that has no more 
approval than candidate C, then C has a chance of winning.
