      If you try to give that calculator a truncated ballot it will just
      turn it into the sort of ballot you like.<br>
      <br>
      How do you think equally-ranked ballots should be counted in a
      pairwise comparison?  A half-vote to<br>
      each or zero to both?<br>
      <br>
      So you can't actually point to any election example where the
      Plurality criterion bars from winning the candidate <br>
      that you think should have won?<br>
