It would be great to be able to vote for every candidate in an election instead of only once and you can decide to upvote, downvote, or not vote for any candidate. This way you never “throw away” your vote and extreme/hated candidates can be downvoted so if im not a fan of any candidate but one is particularly awful I can downvote that one and not vote any I don’t like while still making my voice heard that I definitely don’t want this specific candidate
Edit: Combined Approval Voting is what I want and its used by to elect the Wikipedia Arbitration Committee and the Secretary General of the United Nations
Edit 2: You can learn about and try different voting methods in this amazing project https://ncase.me/ballot/
Personally I prefer the idea of ranking each candidate in order of preference, ie “this is my favorite candidate, this is my second-favorite, and so on for all the candidates with enough support to be on the ballot”. I feel like it has more granularity than an upvote downvote system would have.
