    I will say, the voting system that we advocate for is important.

    There are three common choices. RCV, Approval, and STAR.

    RCV has some momentum, but is just a bad voting system. It’s arguably worse than Fist Past the Post, because in a way, it is FPtP. Or rather, it’s several FPtP elections in a row, dropping the lowest each time.

    Which is where a problem creeps in. See, it’s drop lowest, and then never hear from that person again. So if they are the literal second choice of 99% of voters, they’re dropped in the first round and never seen again.

    This leads to ballots that look like this;

    1 - dropped in 4th round 2- dropped in 1st round 3- dropped in 2nd round 4- dropped in 3rd round 5- Guy you kind of hate and only listed because the rules said you had to list 5. He’s the one who got your vote.

    If you had dropped your first choice, Your second through third might have won.

    There’s also a version of the above ballot that doesn’t have a number 5, in that case your ballot is just thrown out as exhausted. Up to 18% of ballots get thrown out as exhausted. At least that’s what the data from California and Maine has said.

    Most countries that use IRV (RCV’s real name) don’t publish any election data, so we use what we’ve got.

    Anyway, Approval and STAR are both immune to shit like the above, because how you rate one candidate has zero bearing on how you rate another. Woo for cardinal voting systems.
