Yeah, I thought about that. Basically you can add an epsilon to every <br>
candidate's first preference count and then let epsilon go to zero. This <br>
is equivalent to counting sum over friends A: fpA - sum over defeaters <br>
C: fpC as a two-vector whose first element is just the sum and the <br>
second is the number of friends minus the number of defeaters, and then <br>
using leximax.<br>
<br>
The problem is that this fails clone independence. Suppose A and B are <br>
tied even given the tiebreaker above, and let C be some friend of A <br>
who's not a friend of B. Clone C, then A wins.<br>
