Sure, but I sometimes over-word things to be on the safe side.

Yes, one thing that I sometimes point out is that Condorcet is
nearly the only method where it's never necessary for voters to
not rank their favorites alone in 1st place.
The wording you suggest is a way of putting the lesser-of-2-evils

Yes, though it's important to mention that majority-rule property,
I've been getting away from reference to a majority in my initial
explanation because, as you say, the property is more general than
that. ...when I say that your vote against your last choice is counted
because you rank a compromise over him, even though you don't rank
the compromise 1st (& are therefore free to rank your real favorite
I should add that, for one of the standards that I proposed, I
meant not just the right to _express_ your preferences, but
the right to have them _counted_.
Someone might say that Copeland counts your preferences. Oh yeah?
It counts them initially, to find out who beats whom, and then
it ignores them. With bad-news results sometimes, for the voter
whose preference has been ignored.
