Let me apply this to my evil testcase. :-)

19x A=DB
19x ABD
1x BA=D

A defeats B by 38 to 1
A defeats D by 19 to 0
B defeats D by 20 to 19.  

On the A->B->D defeat path, A defeats D with 20 positive votes at the 
weakest link, which makes quorum, and A wins.

Yep, this fixes the perverse result I was talking about in another 
thread (where Manoj's proposal causes B to win).  Am I correct, Markus?
