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/
It wouldn’t be a two party this guy versus that guy election though. There would be debates/campaigning and then you upvote/downvote/novote for each candidate running and whoever gets the most wins
