Ok, well what plurality does with cloning winners is so bad that it results in
the partisan stuff that we have today in Washington and elsewhere.

Ok, I can see your point, and I appreciate your satisfying my need to a see
However, I'm still unable to picture the real world consequenses of
minsum/dodgson's problems. Similar candidates would help each other, as opposed
to hurting each other as they do in plurality. Since it requires a
non-condorcet winner for this to even have an effect, how much of a real effect
would this have?
The biggest question for me is whether a method would reduce (or eliminate) the
ugly and destructive partisanship we see in government (at least in the US). I
don't claim to know how dodgson would compare to minmax or beatpath in that
respect. But that's what I'm more interested in knowing.

I have no problem with MinMax, I only explored MinSum, which I now see is called
Dodgson, because I hadn't seen it discussed. Minmax is fine.

Maybe my description was a bit fanciful, but I still think there is potential
value in the idea of tunability. What I think helps people understand things is
graphical output. If you could look at the output of an election (or fictional
election) as a bar graph, then drag little sliders to explore "what-if"
scenarios with different settings and watch the bar graph adjust in real
time...well... I think you'd be surprised at what people can grasp.
In any case, it is the graphical output (and hence scores), not the tunability,
that is my main concern.
