The relative rankings of the methods to produce a Condorcet Winner (CW) are apparently-- 1. Condorcet 2. Approval 3. Bucklin (sum votes at choice levels, 1st, 2nd, etc.) 4. Runoff (top 2) 5. Instant runoff (drop lowest repeatedly) 6. Plurality Any more methods to add ? Why even mention 3-6 when 1-2 exist ?
