Sorry, I started the “Single-winner Asset” topic in the wrong category.
If there are two or more candidates I would approve and two or more I wouldn’t, Approval lets me express that straightforwardly without my having to gamble that one candidate I like would transfer assets to another candidate I like.
Also, Approval is a very simple system. It is FPtP less one constraint.
I hold that Approval gives the voters the same power as any finer-grained Score Voting (Range Voting) system based on addition (not averaging), if the electorate is “large”.
