A Condorcet ranking is an ordering of candidates such that:
- The Condorcet winner, if one exists, is ranked first.
- The secondary Condorcet winner (the new Condorcet winner if the Condorcet winner is eliminated), if one exists, is ranked second.
- The tertiary Condorcet winner (the new Condorcet winner if the Condorcet winner and the secondary Condorcet winner are eliminated), if one exists, is ranked third.
- etc.
and
- The Condorcet loser, if one exists, is ranked last.
- The secondary Condorcet loser (the new Condorcet loser if the Condorcet loser is eliminated), if one exists, is ranked next-to-last.
- The tertiary Condorcet loser (the new Condorcet loser if the Condorcet loser and secondary Condorcet loser are eliminated), if one exists, is ranked third-to-last.
- etc.
Methods that produce Condorcet rankings include Kemeny-Young and Ranked Pairs, and Pairwise Sorted Methods.
