[EM] Re: The "Turkey" problem and limited ranks

Rob,

I'm probably not prepared to answer this to your satisfaction, but there are
a couple of things I can say.

The idea is to collect a balance of information on strict rankings
and ranking priorities.  The turkey thing isn't the main point, but
it's related.

Is that the only advantage you see to Approval ballots?  They also
force voters to indicate preference priorities.

The point of obtaining priorities is that we may be able to avoid a
situation where the strict-ranking CW polarizes people more than the
three-rank CW would.  Neither candidate need be a turkey.  The situation,
quite simplified, looks like:
55: A>B|  (A preferred to B, but given same rank)
45: B|A   (B preferred to A and placed in a higher rank)

These may be in the middle of everyone's ballots instead of at the
top.  In other words, both A and B may well be turkeys.  In any
case, I want to see B elected here over A.

The point is to give Condorcet some knowledge of preference strength,
but with some greater resolution than Approval (two-rank) permits.
