Thanks Kevin, I like the simplicity of that plan -- Condorcet/Approval. Have you thought about only counting the first two rank ballot choices of voters if the Approval step becomes necessary due to a Condorcet cycle? With only three ballot positions in the US I wonder if some voters might rank their last choice third and not really understand they were "approving" that candidate? -- Kathy Dopp http://electionmathematics.org Town of Colonie, NY 12304 "One of the best ways to keep any conversation civil is to support the discussion with true facts."
