Yes, but you can be neutral because all your criteria tell you that both are equivalent or because one of your criteria favours one candidate and another criterion the other one. The first situation is what I call "equivalence", the second is what I call "undecidedness".

Me, too. That was not what I suggested. I suggested the voter should optimally be allowed to express *undecidedness*, that is, be allowed to mark any of the four possibilities
  A>B
  B>A
  A=B
  undecided between A and B
for each pair A,B. Of course that is too complicated for a paper ballot, but I was talking theory here.

Yours, Jobst
