You can use graded ballots in ranking methods, too.  Forest advocates this 
on the grounds that people are familiar with it and it prevents the 
confusion about whether 1 is the lowest or the highest ranking.

That sort of strikes me as a perversion of the phrase for the benefit of 
IRV.  Or perhaps, for the denigration of Approval.  I mean, who cares (for 
the purposes of the spirit of 1P1V) how the electoral system cranks through 
all the names on a ranked ballot or on a list of approved candidates?  All 
that matters is that, at the end of the election, I don't have a way of 
making my vote more powerful than someone else's.

How about this phrasing:

***A voter can have at most one vote that contributes to the election of a 
candidate.***

By the way I wrote it, IRV, plurality, and Approval clearly pass, and Borda 
clearly fails.  Condorcet is a funny case because there are many (n 
squared, minus n, divided by two) contests going on at once, but clearly 
1P1V is maintained in each one.
