Each referendum or proposition is placed on the ballot by someone, who can be authorized to withdraw it.
Obviously, there is no empirical evidence there will be a negative perception that the winner has changed wrongfully after a candidate's withdrawal influences the outcome. I do not agree that the possibility some voters will view the outcome negatively is sufficient reason not to allow withdrawal. Think about the candidates' incentives. The candidates will expect scrutiny of their decisions whether or not to withdraw, and if their decisions do not pass muster then their political futures will be undermined. Also, think about the voters' learning process. I do not believe it would take more than one or two election cycles before most voters understand the usefulness of the withdrawal option to society. If candidates may not withdraw after the voting, some of them may be forced to withdraw before the voting (also known as "deciding not to run, out of fear of being a spoiler that worsens the outcome") or some voters may be induced to vote insincerely. I've observed considerable voter negativity regarding not having a good enough candidate to vote for on election day, in systems where spoiling prevents candidates from running, and having to "hold one's nose" while casting a vote for a less-preferred candidate. I expect there would be considerable voter negativity regarding the need to vote strategically in systems that do not permit withdrawal. A couple of weeks ago in this thread of messages, I wrote about voting methods in which each candidate publishes an ordering of the candidates prior to election day. Another advantage of such methods (besides simplifying election day for the voters) is that the published orderings would serve to forecast the candidates' decisions whether to withdraw. A candidate whose withdrawal decision is inconsistent with his published ordering would presumably attract intense scrutiny, undermining his political future. Also, the candidates' orderings would help prepare voters in advance for the withdrawal decisions, and (the few) voters who might respond negatively could choose to vote for someone else. --Steve ---- Election-Methods mailing list - see http://electorama.com/em for list info
