Continuation: What message would that send to the 'winning' candidate? Even though Candidate D 'won', what did he 'win'? Not even a simple majority, let alone a mandate; he takes office knowing that 95% of the voters opted for either the other candidate, or to withhold their consent from both. Even today, candidates in three-way races who don't win by 50+%, tend to be very circumspect in office, because they know they don't have the majority of popular support. I'm not saying this is a great idea, just an idea that's (1) different, (2) likely to get the attention of both parties, since one or two points can now change the outcome of elections, (3) grassroots and can go national without a lot of money or organization, and (4) peaceful.
