First, people wouldn't have to vote "useful", for the candidate that might win rather than their true favourite. It's the case in France where we always have 5-6 left parties. Also, it would show how "approved" each canditate is.
With this system, everyone can rate all the candidates (0-7 is the proposed scale), then the one with the best median wins. It would tackle so many of the main issues we have with voting today.
I have been dreaming we use that voting system for years now. In fact, since I first heard of it, democracy sounds plain stupid to me. The way we vote is broken in so many ways.
My neighbors car got broken into last night. They took nothing of value but dumped everything all over the street for the entire block. He is understandably pissed. What a shite start to the morning.
