    Top -4 primaries are (pick-1 primaries). They’re garbage.
    He makes a very short mention of how primaries should be run (with Approval voting).
    Redistricting should be done with ungameable shortest splitline algorithm to end *all* shenanigans (for good or bad)
    But the real solution isn’t even mentioned STAR Voting. Cardinal method are much better systems over ordinal.
    As an electoral reform advocate I’m glad these places have banned RCV.
    Ranked Choice Voting is a truly bad system in practice and math and if this guy is an expert he would know that.
    Imo we shouldn’t have primaries. We just need a cardinal ballot (Approval or STAR) for a general election with a wide field of candidates. This has many benefits that aren’t even mentioned as problems in this video – like money in politics. This is one of the least informed electoral reform TED talks I’ve watched.

      @@MichaelBerthelsen Real world implementation is terrible. He even says, “Top 4 Primary” in Alaska. This is a mitigation system of one of the flaws of RCV because the ballots expand exponentially as the number of candidates increases. It’s also a terrible mitigation for several reasons: each voter can only choose to support one candidate in the primary just like FPTP. Historically primaries have far lower turnout than the general. That means that anyone that misses the primary will not be able to express their full political support to any candidate that was knocked out. That’s just one issue. Alaska could have chosen to use Approval Voting to run their open primary and it would be far less bad. But as I said that’s just one flaw. RCV also doesn’t do away with the spoiler effect. There’s a great video called, “How IRV Betrays Your Favorite Candidate” that explains the Center Squeeze Spoiler Effect of RCV which happens every single time you have three candidates and the centrist gets eliminated. I have more flaws and reasons why cardinal systems are far better but I’ll wait for any follow-up questions you might have.

      @@MichaelBerthelsenhere’s just another quick one- RCV doesn’t allow voters to express their full political support all at once. And it’s fairly intuitive to understand you can only support your first choice until that first choice is eliminated. It makes much more sense to aggregate everyone’s full political support at once. RCV is a very poor voting experience. Imagine ranking 32 flavors of ice cream, keeping that list in your head and putting it into that candidate x rank grid ballot. Insanity. Now imagine an alternate system where you give your favorite flavor a score of 5, least favorite a score of zero and then score the last 30 with respect to those where equal ratings are permitted. It’s a fairly easy mental task. There’s also a lot more information that can be gleaned from the elections resultant data about the electoral preferences of voters. Anyway again my list of RCV’s flaws is still not exhausted, but I need to get back to work.

    Democracy is barely functional. We stopped trying to improve and find a better system.

    Democracy is the best form of government we (humanity) designed so far. But that doesn’t mean it’s any good. I wouldn’t want to go back to other forms of governance from history, but there is a perception that Democracy is amazing and there is no need to move past it. It’s absolutely not. It’s a deeply flawed system that just barely not collapses completely.

    Around the 9 minutes You call a new voting system called, Top four primary vote, here in England we a have been pushing for a reform of the two party system,

    But not the system of multi-party voting as in Europe were in the case of France only the top two or three candidates are put forward for election a week after the first vote if no candidate gets 51% of the vote, this as resulted in the top candidate being side lined by the other parties’ votes going against them. Is it unfair, do people feel cheated.

    Or there is the system in other European of a single multi-party voting system were a popular candidate gets more votes then any other candidate, but does not get the required 51% of the vote is again not allowed to form a Government because the other candidate decide who will support who so as to get a total of 51% of the vote to form a government. Again the question is it unfair, do people feel cheated.

    What some people in England have called for a] Voter ID [now done] before casting a vote. Then b] The voter numbers the candidates on the form in order of preference. Then it is both a secret vote, and the counting is fairly simple. All the votes are totalled up if any candidate gets 51% on the first count the candidate is deemed elected.

    If 51% vote is not achieved, then the candidate with the lowest vote has his/her votes counted and the second choice is added to the remaining candidates until a candidate gets 51% of the vote. If a candidate does not achieve 51% of the vote again the lowest candidates’ votes are counted and the second preference is transferred the candidates until 51% of the vote is achieved.

    It is a secure system, people only vote once and no political gerrymandering or tactical voting can be done, if a second vote is required. This system of voting is called the transferrable vote system. Yes, it requires honesty within the counters, but with adequate supervision that is not a problem.

    Lastly, we have asked for the postal vote to be much stringent and unless a severe illness, or disability prevents the voter turning up in person, them ALL votes must be in person.

Interestingly, a president was elected from a third party this time, breaking the long-standing trend. In previous elections, we’ve seen heightened polarization, with voter behavior appearing more divided than it actually was. Looking ahead to the parliamentary elections, redistricting should be seriously considered, especially as demographics shift over time.”

    With ranked choice voting, the Electoral College would become superfluous, and gerrymandering would become pointless.
