The "Surprisingly Popular Vote" actually works quite well:

Although it seems like there needs to be more research on the boundary cases

Are there people that actually want to implement "Surprisingly Popular" for voting in political candidates? It seems useful for things like finding the correct answer to a factual question, but I have no idea how it would work in politics.

It's less about politics than it is about the "wisdom of the crowds". For example, it'd be really useful to get info from traders if they have special information about how the market will move.
