For reference, I repeat Markus' example along with some of my comments from 
my May 9 message:

   26 voters vote:  C>A>B>D
   20 voters vote:  B>D>A>C
   18 voters vote:  A>D>C>B
   14 voters vote:  C>B>A>D
    8 voters vote:  B>D>C>A
    7 voters vote:  D>A>C>B
    7 voters vote:  B>D>(A=C)

D- 

51 AB 49
45 AC 48
40 AD 60
35 BC 65
75 BD 25
40 CD 60

No Condorcet winner.

Choice Votes

   1       1+2

A  18     51
B  35     49
C  40     40
D   7     60  highest/earliest majority

  100    200

Which choices can get YES majorities (regardless of the other choices) ?  
(especially B and/or C and perhaps even A or D ? )
