    I don’t understand why the USA doesn’t use preferential voting like Australia does: https://www.chickennation.com/voting/

    Instead of just picking one candidate/party, you number them based on your preferences. First all the #1 votes are counted. If no party gets the majority (over 50%) of votes, the party with the least number of votes is removed, and for everyone that voted for them, their #2 votes are used. Repeat until someone wins.

    Independents (what you call “third-party” in the USA) can win, and any party that gets over 4% of the #1 votes gets election funding from the government (a fixed amount per vote).

      Because both of the major parties benefit from excluding the competition.

      It’s kind of like, if your car won’t start, you need to take it to a mechanic, but because it won’t start, you can’t drive it to the mechanic. We need to change how our elections work because FPTP prevents us from implementing the policies we want, but it’s precisely because it prevents us from implementing the policies we want that we’re unable to change it. It’s a catch-22.

      No party should ever have over 50% of power. Hell, no party should have more than 30%. Different parties should work together always to ensure one single party can never project it’s power over those that don’t want it

      IRV, or RCV as it’s being sold here, has a lot of problems.

      It’s the only voting system in existence where ranking someone higher on the ballot can cause them to lose the election.

      Australia gets around most of the problems of IRV by just not telling people any information about the vote except the winners.

      Also you only use straight IRV for a single part of your government.

      The US would use it for every part of our government. It would be a shit show.

      Which is why RCV has been banned in half a dozen states.

      Now, there are better voting systems. Systems that live up to the hype.

      STAR is the single best voting system designed to date.

      As a cardinal voting system, it’s actually immune to the Spoiler Effect.

        Interesting… Do you have an example of this?

          We’ve seen it happen in actual elections, as shown in the Wikipedia link.

          RCV is just a flawed system, which is expected for something created by a couple of guys 150+ years ago.

            Disclaimer: I wrote this all for myself not to change your mind or argue. Helps if I write down my thoughts and I don’t see a problem sharing. Feel free to discuss if you like.

            35 voters: Alice > Carol > Bob

            35 voters: Bob > Carol > Alice

            30 voters: Carol > Alice > Bob

            Vs.

            41 voters: Alice > Carol > Bob

            29 voters: Bob > Carol > Alice

            30 voters: Carol > Alice > Bob

            Alice wins

            Vs.

            Carol wins

            Say you have:

            41 voters: Republican > Third-party > Democratic

            29 voters: Third-party > Democratic > Republican

            30 voters: Democratic > Third-party > Republican

            If those 29 voters couldn’t vote Third-party they would vote Democratic. So when the Third-party candidate is knocked out, their votes should favor their second pick. Democratic wins 59-41.

            If it was:

            41 voters: Republican > Third-party > Democratic

            29 voters: Third-party > Republican > Democratic

            30 voters: Democratic > Third-party > Republican

            Which makes more since on why the 6 votes moved to Republican because Republican was their second choice.

            Then Republicans win 70-30.

            In America you’d have 4 basic senarios

            25 voters: Republican > Third-party > Democratic

            25 voters: Third-party > Democratic > Republican

            25 voters: Third-party > Republican > Democratic

            25 voters: Democratic > Third-party > Republican

            In RCV, Third-party wins.

            Let’s say this

            30 voters: Republican > Third-party > Democratic

            25 voters: Third-party > Democratic > Republican

            20 voters: Third-party > Republican > Democratic

            25 voters: Democratic > Third-party > Republican

            Third-party still wins

            40 voters: Republican > Third-party > Democratic

            10 voters: Third-party > Democratic > Republican

            10 voters: Third-party > Republican > Democratic

            40 voters: Democratic > Third-party > Republican

            It would be a tie

            45 voters: Republican > Third-party > Democratic

            10 voters: Third-party > Democratic > Republican

            5 voters: Third-party > Republican > Democratic

            40 voters: Democratic > Third-party > Republican

            It would still be a tie

            45 voters: Republican > Third-party > Democratic

            5 voters: Third-party > Democratic > Republican

            10 voters: Third-party > Republican > Democratic

            40 voters: Democratic > Third-party > Republican

            Republicans win

            Let’s change it to this:

            35 voters: Alice > Carol > Bob

            35 voters: Bob > Alice > Carol

            30 voters: Carol > Alice > Bob

            Vs.

            41 voters: Alice > Carol > Bob

            29 voters: Bob > Alice > Carol

            30 voters: Carol > Alice > Bob

            Alice wins

            Vs.

            Alice wins

            They couldn’t make their whole point if you just switched Alice and Carol. And it makes much more sense that someone with Alice second would change it to Alice first.

            But when 29 votes still hold Alice as last, it does have some weight.

            Something just seems off about it and it’s because they cherry picked a senario that would work for their point.

            Alice > Carol > Bob

            Alice > Bob > Carol

            Bob > Alice > Carol

            Bob > Carol > Alice

            Carol > Alice > Bob

            Carol > Bob > Alice

            There are 6 ways to vote and they leave out half of them. Then they make Carol supporters favor Alice as their second choice.

            20 voters: Alice > Carol > Bob

            15 voters: Alice > Bob > Carol

            15 voters: Bob > Alice > Carol

            20 voters: Bob > Carol > Alice

            20 voters: Carol > Alice > Bob

            10 voters: Carol > Bob > Alice

            Carol eliminated, +10 Bob +20 Alice. Alice would win.

            If 5 voters from Bob > Alice > Carol were moved to Alice > Bob > Carol

            20 voters: Alice > Carol > Bob

            20 voters: Alice > Bob > Carol

            10 voters: Bob > Alice > Carol

            20 voters: Bob > Carol > Alice

            20 voters: Carol > Alice > Bob

            10 voters: Carol > Bob > Alice

            Alice would win

            What if everyone from Bob > Alice > Carol moved to vote for Alice > Bob > Carol

            20 voters: Alice > Carol > Bob

            30 voters: Alice > Bob > Carol

            0 voters: Bob > Alice > Carol

            20 voters: Bob > Carol > Alice

            20 voters: Carol > Alice > Bob

            10 voters: Carol > Bob > Alice

            It would be a tie.

            In bold are the three they selected:

            20 voters: Alice > Carol > Bob

            15 voters: Alice > Bob > Carol

            15 voters: Bob > Alice > Carol

            20 voters: Bob > Carol > Alice

            10 voters: Carol > Alice > Bob

            20 voters: Carol > Bob > Alice

            5 voters from Bob > Carol > Alice moved to Alice > Carol > Bob. Just like their example.

            26 voters: Alice > Carol > Bob

            15 voters: Alice > Bob > Carol

            15 voters: Bob > Alice > Carol

            14 voters: Bob > Carol > Alice

            10 voters: Carol > Alice > Bob

            20 voters: Carol > Bob > Alice

            Alice 41

            Bob 28

            Carol 30

            Bob is eliminated.

            15 votes goes to Alice. 14 goes to Carol.

            Alice still wins.

            But they set it up like:

            20 voters: Alice > Carol > Bob

            15 voters: Alice > Bob > Carol

            0 voters: Bob > Alice > Carol

            35 voters: Bob > Carol > Alice

            10 voters: Carol > Alice > Bob

            20 voters: Carol > Bob > Alice

            5 voters from Bob > Carol > Alice moved to Alice > Carol > Bob. Just like their example.

            26 voters: Alice > Carol > Bob

            15 voters: Alice > Bob > Carol

            0 voters: Bob > Alice > Carol

            29 voters: Bob > Carol > Alice

            10 voters: Carol > Alice > Bob

            20 voters: Carol > Bob > Alice

            Then when Bob is eliminated all 29 votes go to Carol.

            Then they say “It’s unfair that Carol wins”. When in reality those 29 people would prefer Carol over Alice.

            RCV might have some flaws but that article has some flaws.

            I haven’t looked at the others. I might later.

              The first article is from someone who wants to save RCV, despite that one flaw that they’ve drilled into.

              The problem is that it’s a known attack vector, the Wikipedia article talks about how it was used intentionally by a political party in 2005 in Germany to effectively steal an additional seat in their parliament.

              My second link is a deeper dive into more of RCV’s many flaws. Because why stop at monotonicity? Seriously, the fact that increasing support can cause a candidate to lose, and not just lose but elect the worst choice, is insane.

              That fact that there are more flaws, just as game breaking, means we should all follow the example of the Marquis de Condorcet, the guy who invented RCV, abandoned it because he saw how broken it was.

              Then you have the lying liars at FairVote saying that the Condorcet criterion doesn’t matter in elections.

              The Condorcet criterion is that if you were to hold a series of one on one elections between all candidates, the winner of those should be the same winner of your election system. RCV fails this in most elections, which is why Condorcet abandoned it.

              It wasn’t until about 30 years after Condorcet’s death that an Englishman revived the voting method, but added a proportional twist. It still had all the flaws that Condorcet wrote about, but Condorcet was French, and lost the political games of the French Revolution, so he was mostly ignored.

              As a side note, the political writings of Condorcet should be required reading. The guy wrote this in 1790

              ‘The rights of men stem exclusively from the fact that they are sentient beings, capable of acquiring moral ideas and of reasoning upon them. Since women have the same qualities, they necessarily also have the same rights. Either no member of the human race has any true rights, or else they all have the same ones; and anyone who votes against the rights of another, whatever his religion, colour or sex, automatically forfeits his own.’

            Thanks for the links. I appreciate it! Now I understand the issue.
