Here's an example of the kind of Bad Thing that can happen with 
Approval. There are 3 candidates (A, B, C) and 10 voters. I am using 
signed CR's in the range -1 to 1 (CR>0: approve, CR<0: disapprove). 
Following are the sincere CR's:
9 voters: A(-1), B(0.1), C(1)
1 voter: A(-1), B(1), C(-0.1)
avg CR: A(-1), B(0.19), C(0.89)
approval: A(0), B(10), C(9)
plurality: A(0), B(1), C(9)
