Coombs' method

[1] The method fails most voting system criteria, including Condorcet's majority criterion, monotonicity, participation, and clone-independence.

[1] It was described by Edward J. Nanson as the "Venetian method"[4] (which should not be confused with the Republic of Venice's use of score voting in elections for Doge).

Otherwise, the candidate ranked last by the largest number (plurality) of voters is eliminated, making each individual round equivalent to anti-plurality voting.

[5] This variant of the method can result in a different winner than the former one (unlike in instant-runoff voting, where checking to see if any candidate is ranked first by a majority of voters is only a shortcut that does not affect the outcome).

[6] As a result, voters have a strong incentive to rate the strongest candidates last to defeat them in earlier rounds.
