Normal Proportional Approval Voting would give it to ABC, ABD or ABE based on satisfaction. Everyone has voted for one of the elected candidates and some get two. Whereas with CDE, it's purely one each, but as you say this is envy-free. While I can see the merits of the envy-free argument, I wou

Forest and I were discussing PR last week and the following situation came up. Suppose there are five candidates, A, B, C, D, E. A and B evenly divide the electorate and, in a completely orthogonal way, C, D, and E evenly divide the electorate. That is: One-sixth of the electorate approves A a
