Suppose you have 16 candidates to rank. You know how each of them stands
on the four issues that you consider vital.

D- Some issues are much more important than others - war or peace, making
such and such a crime, taxing such and such, spending $X or $Y for such and
such, etc.
That is, there is a major weighting effect on very specific issues by some
voters (especially, in effect, voters somewhat obsessed on one issue -
aardvarks to zygotes and everything in between).
