Looking ahead, Plurality lets the voter present a small amount of
information; Approval a bit more; and Condorcet additional - each such
as the previous methods do not permit.

Agreed that Approval allows approving more than one, and that each
approved is preferred over each unapproved, just as the one approved
in Plurality is preferred over all others.

Now it is time to be more careful.
In Condorcet if I give one rank to all I prefer I have given the same
preference to those ranked over those unranked as I could do with
But ability to use multiple ranks in Condorcet or Kemeny gives me
additional power - among the ranked candidates my preferences can be
unequal and I show this by ranking higher each that I prefer over
other ranked candidates.
Condorcet perhaps should be described as a family of election methods,
usually agreeing as to details such as winner chosen - such as Kemeny.

"2nd set" implies misunderstanding - in the Condorcet family voters
are normally permitted to use more than two rank values.
"FBC" is simply one of many acronyms for which definitions are hard to
find (and to verify having found correctly).
