Jobst, What about this method that doesn't even draw a ballot unless it first eliminates the approval winner?
1. Let x be the percentage of the ballots approving the approval winner X.
2. Elect X with probability g(x), else elect the favorite of a randomly drawn
ballot.
This method lacks the "bullet voters' guarantee" of proportional probability,
but almost any increasing pdf g solves the
challenge problem.
