Condorcet: A is the first choice of the majority, so he defeats all other
candidates pairwise and wins.
Borda: B gets 34*2+66=134 points, A gets 66*2=132 points, C gets 34 points.
Saari: Anybody who thinks A is the favorite of the electorate really
doesn't understand how to deduce the true preferences of the voters.
Here's some geometry to show why....
