Line 9:
Condorcet and majoritarian systems choose A, because 2 voters slightly prefer A over C, but C is the best match for ''all'' voters. The fundamental problem with ranked-choice ballots is that they can't capture ''intensity'' of preference, so X/Y's slight preference for A over C is given equal weight to Z's strong preference for C over A.
(Borda also chooses A, since it weights all relative preferences equally when assigning point values, even though the preference strengths are not equal. Borda results in A getting 4 points, C 3 points, and B 2 points.)
