Here are some random observations about the SODA method. There should be a full definition of the method somewhere. If there are three candidates and their declared preferences are ABC, BCA and CAB, the method may introduce some additional problems. If most voters delegate, then we may easily

There has been quite a lot of discussion around the strategic vulnerabilities of Condorcet methods on this list recently. In general I think Condorcet methods are one of the least vulnerable to strategies, and in most typical elections their vanilla versions are simply good enough. In the case

In SODA I'm most worried about the Approval related problems, Do you mean the near-clone game-of-chicken problems? These apply to WV Condorcet methods too (although less-obviously to an unsophisticated voter), and with margins, there is the opposite burial problem: 35: AB 25: B 40: C What
