The majority approval filter is a cousin of the Smith filter, but Smith-Condorcet won't leave a vacuum of power so it would be less controversial. Is it worth worrying about extreme examples? The replacement of candidate names (like Hitler, etc.) with neutral letters obscures the issue of whether the example is politically realistic, seems to me. >In a small election, there is obviously a much higher possibility >of ties. How many voters are necessary for a "large" election ? >Answer- the method used should not matter regardless of how few or >many voters there are. Is is wise to talk about the tie-breaker portion of the method before people understand the main portion, if that's all that would be used 99.9999999% of the time? By the time a tie actually occurs in a large election, all the people who we've taught the tie-breaker will be deceased. If a tie occurs, does it really matter much how the tie is broken, as long as basic democratic principles won't be violated? It's not nearly as important as getting the basic method done right. I wouldn't oppose Condorcet//Random if that's what a group desired, but Condorcet//Plurality-ext is simple and practical. Maybe the tie-breaker should be in the fine print, or left unchanged by the sw reform. ---Steve (Steve Eppley [EMAIL PROTECTED])
