This is a wonderful example of the fundamental flaw with this class of 
argument that I mentioned before.

Why assume that only the A voters would attempt to manipulate the 
election by changing their votes?

If the B & C voters, who certainly prefer D over A, get a hint that the 
A voters are attempting to manipulate the election, they can bury A and 
promote D and give D the victory - 500 to 499, which was the sincere 
outcome to begin with.
