I can only think of a few ways to derive the required information from ballots (I don't think I even want to get into aggregation methods here): 1) allow the voters to assign a rating to each candidate, so that the B+C will be chosen if their combined score is higher than A, for example. This mi

A theoretical, though impractical way to handle this would be as follows: Have independent ballot-choices for place 1, place 2, etc. which each allow the ranking of all candidates. The voter may choose to rank A>B>C>D... in every position, in which case their "vote" degenerates into some variation

Condorcet methods like beatpath winner can be used to obtain a ranking of the candidates but they don't seem to be good for elections in which the goal is proportional representation. I'm curious whether people know about generalizations of beatpath winner that make sense for this purpose. There

There is no way to accurately determine approval voting results using this input format. About the best you can do is to assume that for the A>B voters, half approve both A and B, and the other half approve only A. This would make approval voting equivalent to Borda, at least where fully ranked

Hello List I've recently been working on a spreadsheet model to compare various different electoral methods. What it does is generate, for a 3 party election, sets of votes for 50 single member districts, based on an inputted set of preferences amongst the electorate and then calculate the results
