That election method where successively that candidate with the lowest
Borda Score is eliminated is one of those election methods which have been
proposed and discussed by Nanson (ca. 1882). This election method meets
the Condorcet criterion and violates the monotonicity criterion, the
consistency criterion, the reversal symmetry criterion, and the clone
criteria.
