Why is it that approval ratings aren't used as the method of electing politicians?
It's just a simple yes or no, whether you think at least one or more of the candidates on your ballot list shares a lot of your concerns, beliefs, et values to at least vote for them
If you don't approve any of them, just don't mark them, and write down "I don't like any of these candidates" as a reason
I don't like "first past the post" for this reason... it just perpetuates the idea of "spoiled" votes...
There are some really cool electoral methods that are used in some niche situations (e.g. the Schulze method). Obviously wouldn't work to elect a government, since that would not massively benefit the ruling class as the current methods do.
