Nanson's method

The Borda count can be combined with an Instant Runoff procedure to create hybrid election methods that are called Nanson method and Baldwin method.

Satisfied and failed criteria

The Nanson method and the Baldwin method satisfy the Condorcet criterion: since Borda always ranks the Condorcet winner over the Condorcet loser, the Condorcet winner will never be eliminated. They do not satisfy the Independence of irrelevant alternatives criterion, the Monotonicity criterion, the Participation criterion, the Consistency criterion, the summability criterion and the Independence of Clone Candidates criterion, while they do satisfy the Majority criterion, the Mutual majority criterion, the Condorcet loser criterion, Reversal symmetry and the Smith criterion.
