Hello,

I threw together a calculator containing a couple of ideas on guessing the identity (or a
best possible identity) of the "median voter" given cast rank ballots:

One idea is just an adaptation of Ranked Pairs to select a voter instead of a candidate.

The other is to first define a distance metric for any two ballots. Then starting from a
random ballot, consume nearest other ballots continually until a majority is reached. Do
all this repeatedly and check which ballot was brought into the majority the most often.

I may try to come up with more ideas, but I thought two was enough.
