12/30/02 - Alex, Irving still holds the Trump Card: Dear Alex Small,

To which you commented: "Um, if enough people bullet vote, the election is de facto plurality." Donald here: No, you are in error, if some voters still make lower choices, then the election becomes an Irving election. You fail to see the mathematices of what I said. I said `if most of the voters do bullet vote'. I did not say all voters would bullet vote. There is an important difference that changes everything. An Approval election only becomes Plurality if all the voters bullet vote. You are reading into the letters of others what you want to read and believe. Small: "Are you saying that because IRV and Approval can both suffer the same malfunction in practice that IRV somehow has a trump card over Approval?" Donald: Irving has a trump card over Approval because it will not suffer the same effects of bullet voting by most voters that Approval will suffer due to bullet voting by most voters. In an Approval election there is no reason for the supporters of the two leading candidates to make any lower choices, but suppose ten percent do make lower choices. In an Approval election it is to the advantage of the supporters of the lessor candidates to make lower choices, that is, if they wish to have any say as to which of the two leading candidates is to win the election. So, let's suppose fifty percent of the supporters of the lessor candidates make lower choices. Now, let's see what we now have. The lower choices made by ten percent of the supporters of the two leading candidates are not enough to help any of the lessor candidates win the election. But, the lower choices made by the supporters of the lessor candidates can be enough to decide the election between the two leading candidates. This result is the same as if the lessor candidates were eliminated and their votes transferred to the next choices. You should be able to realize that this ending to the election is the same ending as an Irving election and that the Approval election has turned into a variant of Irving. Small: "I'd think both degenerate to plurality if too few voters use the option to support multiple candidates (be it through listing lower choices or approving multiple candidates)." Donald: This is wishful thinking on your part. You know Approval will fail under bullet voting by most and you want Irving to also fail under the same conditions. It's not going to happen, Irving can survive bullet voting by many or by most or by all the voters. Irving will not degenerate, while Approval will degenerate. Irving has far more endurance than Approval Voting. Small: "That's like saying that if two race horses with broken legs are unable to run then one holds a trump card over the other." Donald: The legs of the Approval horse can be broken by the voters, but the voters cannot break the legs of the Irving horse. No matter how many voters refuse to make lower choices in an Irving election the method can still function and finish the race. If you cannot see that Irving is holding a trump card over Approval, then there is something lacking in your understanding of election methods, but you are not alone in that respect on this list, sad to say you're among your friends. Irving still holds the Trump Card. Donald Davison, Post Script: Thanks for the No vote. This is the third or fourth time that Mikeo has tried to have me recalled. Looks like I dodged the `bullet vote' again (pun intended). On Christmas Eve night, Marley's ghost visited me and said that I shouldn't be rude to Mikeo. I'm not afraid of Marley's ghost, but those other two guys scare me.
