Unitary Cardinal Voting is my favorite PR method at the moment, but it requires computers to calculate. At a local level, I don’t see this as particularly feasible or likely to be done, and statewide efforts will require a local template somewhere. In this example (https://groups.google.com/forum/#!topic/electionscience/Rk4ZGf-s-s8) Unitary Cardinal Voting would pick two centrists and one extremist, which I consider a near-ideal result. The only PR method I can think of that (possibly) wouldn’t require computers is Apportioned Cardinal Voting, but that picks 3 extremists in the example, so I consider it to not be worthy. Any suggestions?
(When I say not worthy, I mean that it seems simpler to just go with a consensus single-winner method than to push for a method which may or may not split the voters and is harder to explain.)
