I don't like the idea of yes/no boxes because it would be possible for a voter to approve a candidate who is ranked lower than a candidate who is disapproved. May be the ballot paper could be divided into a left side and right side. Any candidates ranked on the left side are approved while any candidates ranked on the right side are disapproved. I can see the motivation of using Approval to break a Condorcet Cycle. However, there have been posts to this list describing methods that used Ranked ballots in order to derive Approval results. Why can't such methods be used thereby removing the need for voters to mark off an Approval cut-off? Is it the fact that deriving Approval cut-offs from rankings would make ranking strategically more likely? Maybe using (Spruced Up) Gradual Ordinal Information Approval would be better. That is, Forest Simmons "adaptation" of Kevin Venzke's Gradual (Cardinal) Information Approval. Whereas the cardinal version uses the mean average Utility of the candidates that are marked Viable in each iteration, the ordinal version uses the median average ranking of the candidates marked Viable.
