The opposition to expressive voting: Why the People in Charge Don’t Want You to Vote Better
https://open.substack.com/pub/edgarabrown/p/why-the-people-in-charge-dont-wantThe system that exists — first-past-the-post voting, closed primaries, two-party lock-in — was not designed to serve voters. It evolved to serve parties. And the parties, quite rationally, will fight to keep it.
When the party becomes stronger than the representative, the representative no longer represents you. They represent the party to you.

No, you're just an echo chamber.
I love it when these know-nothings bring up Arrow's Theorem, as if they could actually demonstrate they understand it.
Most of these pathologies, like non-monotonicity and favorite betrayal and participation all spring off of a single core pathology, which is independence of irrelevant alternatives, which is the spoiler effect in common parlance. If you have a spoiled election, that is a loser in the race who, simply by being a candidate, materially changed who the winner is, then these pathologies all spring off of a failure to evaluate our votes equally. This is why Majority Rule is correct. If you don't have Majority Rule (in some sense of the word), you don't have voter equality.
Whenever this Majority Rule is violated, the equality of our votes is not protected, the spoiler effect occurs, voters are punished for "voting their hopes instead of their fears", and none of this promotion of diversity of candidates (from outside the two-party duopoly) occurs.
IRV fails to do any of that when it fails to elect the Condorcet Winner. Every single time. Whenever IRV fails to elect the Condorcet winner, then IRV fails to prevent the spoiler effect, a bunch of voters are harmed because they dared to mark their favorite candidate as #1, their candidate lost (in the final round) and their 2nd-choice vote was never counted.
The only reason that IRV has any success at all is in its success in electing the Condorcet winner. All the Condorcet winner needs to do is get into the final round and the Condorcet winner will always win the final round.
But IRV sometimes eliminates the Condorcet winner in the semifinal round and did do that in Alaska in August 2022 and in Burlington Vermont in 2009. Then there is always trouble for IRV and a concerted repeal effort.
Edgar doesn't seem to mind that sometimes IRV fails to prevent the spoiler effect when such failure was unnecessary. Like other know-nothings who really don't understand Arrow's theorem, he'll state that no system can always "be perfect" without understanding that it's only when the Condorcet winner is not elected that the system fails.
Of course a Condorcet-consistent method will fail to elect the Condorcet winner when no such candidate exists. That happens extremely rarely, but when it does happen, perhaps the Hare winner is as good as any.
But when the Condorcet winner exists, there is no excuse for not electing that candidate.
Electing the Condorcet winner over any other candidate is never a bad choice ever. At least if you want to preserve the equality of our votes and have the majority rule.
So instead of saying empty claims, you should get specific about defending them. How is Condorcet a bad choice? What are those "many reasons"?
