SODA voting (Simple Optionally-Delegated Approval): Difference between revisions

In this simplified example, all the residents of each city agree on the rankings of all the other cities, so there would be no reason for anybody to do anything but bullet vote. Memphis has the first option to delegatechoose approvals for its delegated votes, and, as the leader, decides not to approve noone but itself. Nashville goes second; it is the pairwise champion (Condorcet winner), so it also declines to delegateapprove any of its votesothers. Chatanooga and Knoxville would delegate toapprove each other and to Nashville, to prevent Memphis from winning. Nashville would then be the winner, with 58% approval after delegation.

Chatanooga could, before the election, not include Nashville in its preference list, hoping to force Nashville to delegate toapprove it. But in that case Memphis would delegate toapprove Nashville to prevent Nashville from being forced to hand the election to Chatanooga, and so Nashville would win with an even larger majority. Therefore, Chatanooga will not attempt this.
