Exactly. You're falsifying an indifference, but you're not falsifying a
preference. An indifference certainly is not a preference.

Elsewhere in that sincerity definition, I _do_ speak of failing to vote a
felt preferrence.

No, because my definitions of voting X over Y are entirely independent of
balloting.

But certainly if you rank X last, and you don't rank Y, then, by all of my
definitions, that is voting X over Y.  Likewise by everyone's intuitive
interpretation.

My definitions of voting X over Y don't need different wordinsfor different
methods.

Certainly, and all of my definitions of voting X over  Y would agree.

(...unless it's a definition-version that is with respect to the method in
which takes place the particular voting being discussed, and that is a
method that doesn't have that interpretation.)

Wait a minute. If you ran A last, an there are unranked candidates, then my
method nonspecific definitions would say that you're voting A over
someone.  My definitons with respect the the method in which takes place
the voting that's under discussion would or wouldn't call that "not voting
A over anyone", depending on whether they count that as voting A over
someone.  Of course every rank method that we discuss here, and probably
every rank method that allows ranking fewer than all the candidates, would
say that you're voting A over someone, when you rank A at the bottom of
your short ranking, and there are candidates whom you don't rank
