[EM] Other 2-balloting Condorcet wv enhancements

[MIKE OSSIPOFF]

Sorry, my summary of strategy enhancements for Condorcet wv wasn't complete, 
because I left our some of the other 2-balloting enhancements.

RMDD is a 2-balloting enhancement. There are others too.

I've suggested that, if there's a circular tie in which each tie-member is 
majority-beaten by another tie-member, then there should be a 2nd balloting 
between the members of that circular tie. I've suggested that that 2nd 
balloting be by Approval. But it could also be (like the 1st balloting) a 
Condorcet wv balloting and count.

By the way, the reason for stipulating that all the circular tie members be 
majority-beaten, in these methods and in some of the automatic options, is 
because that's a teltale mark of successful offensive order-reversal.

I've said that the voting system has no way to tell which of several 
majority-beaten candidates is a CW. The more automatic options that I 
described in my previous posting--the Order Estimate Option and the 
Unanimity Option, are ways in which the voter can instruct the method to 
make that determination.

But  if a circular tie with all its members majority-beaten always triggers 
a 2nd balloting, then the voters themselves can be the ones to judge what 
has happened, and if a CW has been the victim of offensive order-reversal, 
and can act accordingly in the 2nd balloting.

With good enough information from the 1st balloting, Approval would be fine 
in the 2nd balloting. Also, Approval couldn't result in a 2nd majority 
circular tie, and the need for still another balloting.

James A. also suggested some many-balloting (more than 2 ballotings) 
enhancements, but it seems to me that it would be much more difficult to 
propose to the public something that can need more than 2 ballotings.

The 2-balloting enhancements that I suggest are a compromise between 
1-balloting wv and RMDD.
They sometimes trigger a 2nd balloting, but they don't require disqualifying 
all the candidates and having all new ones in the 2nd balloting. Of course 
they don't have RMDD's SSSC compliance either.

By the way, these 2-balloting methods don't trigger the 2nd balloting in 
exactly the same conditions that RMDD does. If there's a majority circular 
tie, these 2-balloting methods call for another balloting. But RMDD, if one 
or more candidates outside the circular tie isn't majority-beaten, would 
apply Condorcet wv to the winners, the candidates who haven't been 
disqualified by a majority defeat.
RMDD doesn't need a 2nd balloting unless all the candidates are 
majority-beaten.

Of course there could be a variation of RMDD which would also disquailfy 
candidates for not being in the circular tie. I'd call that RMDD2. So far, I 
prefer RMDD, which less often needs a 2nd balloting with new candidates.
