That argument makes sense after the election, once the A or C voters  
know for certain that C or A, respectively, would have won had it not  
been for B. But the argument fails *before* the election. Given the  
implied utility function of this election, both A and C voters have a  
strong incentive to bury B if they think their own candidate has a  
good chance of winning outright.
