You’re correct in all this. I simply think the real world application of approval is unlikely to typically end up with results like this. It’s not impossible, but it could easily happen. The only thing ranked choice has on approval is that you can… well, rank your choice, providing weight to some candidates over others. But the standard ranked choice center squeeze effect is a pretty big problem to me. Also, sometimes the rank is arbitrary between two candidates you like equally well.
I have heard an interesting idea of using a scored approval instead. Where for n candidates, you rank the candidate you would most approve of with the number n. Then each other candidate you approve of in descending order (n-1, n-2, etc.). So in your ABCD example. If you are trying to make sure D doesnt win, you would rank A as 4, B as 3, and C (the lesser of two evils) as 2, and leave D blank. You then add those scores up and the winner is the one with the highest score. This would provide weighed results for the approval to your most preferred candidates, allowing you to give a measured amount of support to any given candidate. However, this still has the arbitrary ranking issue for similarly liked candidates. Maybe you could vote whatever rank any number of times you wish for any candidates? Idk. I’d have to try it or see some examples to think it through properly.
