[EM] Better short definition of voting X over Y. Long definition is official, though.

[MIKE OSSIPOFF]

First I want to emphasize that I adoped Richard's shorter definition 
believing that it would give the same answer as my definition, at least with 
all proposable methods, or maybe with all methods. So, when there's a case 
where the 2 definitions give different answers, it's obvious that my own 
definition is the one that appllies.

My own longer definition will be my definition of voting X over Y. But I'll 
still often, maybe usually, use the shorter definition, though I hereby 
state that my own definition is the one that applies when the two 
definitions differ.

Here's my improved short definition:

A voter votes X over Y if: If we count only his/her ballot, with all but X & 
Y deleted from it, then X wins and Y loses.

[end of short definition of voting X over Y]

That definition avoids the unintended loophole of its previous version, and 
therefore better carries out my intent for the definition. But I don't know 
that the unusual, implausible practice that it speaks of, counting only one 
ballot, couldn't lead to other problems. For instance, someone could speak 
of a method which explicitly requires more than one ballot, or whose results 
are unexpectedly affected by counting only one ballot.

Therefore my own longer definition is my actual definition of voting X over 
Y, though I'll often use my short definition, due to its brevity, with the 
understanding, stated in this messgage, that if they differ in their 
answers, my long definition is the one that applies.
