We show that there is a sense in which the Condorcet method (simple majority rue) is less vulnerable to strategic voting than any other reasonable voting rule satisfying independence of irrelevant alternatives (IIA). If we drop the requirement of IIA, then Condorcet and the Borda method (rank-order voting) are jointly the least vulnerable to strategizing.
