[EM] Re: IRV is summable (a little)

[Dave Ketchum]

When I look I see an argument for Condorcet:
     On A vs B 70 prefer A while only 20 prefer B - strong anti B
     On A vs C 30 prefer A while 60 prefer C - weak pro C
     On B vs C 50 prefer B while 40 prefer C - real weak pro B.

So Consorcet Gives it to A and there should be less complaints than B or
C winning should inspire.
