Re: Filling a vacated seat using STV

Thank you, but in your example, with the Droop quota (specifically quota 34)
I also get candidate C as the new winner, yet the second winner comes out as
candidate D or B because they have the same number of votes. With the Hare 
quota, the new winners are candidates C and B; thus candidate A would be 
replaced by candidate C. And is it possible to find a counterexample for the
unrounded Hare quota?
