Those two parties won't keep slapfighting for an uneven split of 60% of the vote, while this third party takes power with 40% of the vote. They will merge. Or the smaller one will simply vanish, if its voters prefer the bigger loser to the plurality winner.
Even in the US, where plurality has a hideous repeated bottleneck on which two parties can meaningfully exist, we did not always have these two parties.
... wait, Sri Lanka has ranked ballots! What the fuck? They're not even using Plurality, they're doing RCV!
Ranked Choice is a hot mess on its own, but-- oh for fuck's sake I'll just use the example I always use. Say an election goes like this:
40% vote A > B > C.
35% vote C > B > A.
25% vote B > C > A.
Plurality says A wins, because Plurality sucks. You don't even need a bare majority. You just need everybody else to split up.
RCV says C wins: B has the fewest top votes, so they're eliminated. The race becomes 40% A > C versus 60% C > A. Better... but still wrong, because 65% of people would prefer B > C.
Condorcet methods like Ranked Pairs get that right. They model every runoff: A vs B is 40-60, A vs C is 40-60, B vs C is 65-35. B wins every 1v1 and is obviously the best candidate according to these voters. The supermajority prefers B.
And of course Approval Voting is just letting people check multiple names, and it somehow matches Condorcet results when enough people vote, because you are unique, just like everybody else. Genuinely there is no good reason we're not doing Approval by default.
Is there something I’m missing? They won because they got the most votes between three parties(but not a majority) and then the most again during the second round of voting between the top two. They won both times.
Ideologies aside your comment is written like you suspect foul play or something. “It’s broken because they could never win if there was competition” is just a terrible take so I assume I must be interpretting it wrong, right?
The new guy won despite winning <5% of votes in the last election. If people vote for the candidate they like instead of trying to game the system by calculating who they'd rather not win the most, then maybe we can kick out corrupt incumbents and get in fresh faces (they'll get corrupted over time too, at which point you rinse and repeat).
By the sound of things it's more like nobody wanted anything to do with the major-party incumbent. Duverger's law is about how there tend to be two parties. Three and one are equally unstable. When a race becomes a total rout, like a 30-point spread, that dominance can be seen as a power vacuum.
... also, Sri Lanka has ranked ballots. It's not a Plurality voting system. They have an automatic runoff. That's one of the more obvious fixes that allows people to even consider supporting a third party, without playing Russian roulette against their own foot.

Emphasis on the 'tends'. It's a probabilistic observation, not a law of nature. Treating it as the latter leads to people acting against their best interests.

You are right, in theory, but please check how many additional votes the winner (or the runner-up) got as second-prefrence votes. It was around 2% of their totals. This is because in practice, most voyers didn't bother putting second and third preferences.
People acting in their best interests is how it happens. It's an electorate avoiding splits. Given the system you're voting under - you should vote for someone who has a chance of winning. Otherwise you might write-in some special favorite candidate that no other human being cares about, and accomplish literally nothing. Voting for a third party with single-digit support is not much better.
People voting against their own interests would be... not bothering to write in a second preference. It is the same fuckup: someone who cannot imagine their very favorite guy losing.
Dude had 3% support despite everyone being able to toss him a vote just-in-case. Anyone who voted for only him, "last election," was a fool. That negligible support is not what made him a viable candidate in the separate election they "just did."
No kidding your choices depend on how other people vote, that's what democracy is. If you can't rally a shitload of people behind your guy... you lose. That part is not the failure of Plurality. Plurality blows because two similar groups can be wildly popular and still get destroyed by a minority of schmucks.
The winner of this election was not decided by everyone seeing through The Matrix or whatever and deciding to defeat a broken electoral system. It sounds like 95% of them are functionally unaware of which electoral system they have.

Or they were the people who made this year's result possible.

Yes, but you show that so-and-so's platform has x amount of support, putting them in a better position next time around.

It's incredible how one can see some piece of evidence that contradicts their pet theory with their own eyes and say, no, the reality is wrong and my theory is right. I mean, it makes sense sometimes - the discovery of Neptune is a famous example - but in general, it is better to adjust theory to fit the facts, rather than the other way around.
If most voters keep picking one guy, these three parties will become two parties, or the two more-similar parties are fucked. That is what Duverger's law is about. It doesn't mean third parties can never win - it means a three-party system cannot last.
If Sri Lankan voters remember how their own goddamn electoral system works, they can have a four-party system, no problem. But as you point out, they're acting like they have America's elections, where this schmuck who got 17% is now a massive liability to the runner-up who got 33%. If those two presumably-liberal blocs got together, they could handily oppose the leftist bloc. But if they're competing for the same exclusive votes then they'll both become irrelevant.
Sri Lanka already fixed the thing that breaks Plurality. Their voters just aren't using it, for some goddamn reason.
Or they were the people who made this year’s result possible.
Objectively not. Every single person who wanted him, last time, could have listed him... also. They sure didn't. His support was three percent. That's not a viable path to power, that's a punchline.
He's done stuff since then. Right? Campaigned, presumably? Been in the news? Built up the expectation that a meaningful number of people would prefer him over other major candidates? That is what made this result possible. Losing a prior election is not a prerequisite.

It would be useful if you tried to understand Sri Lanka's political system before you made such comments. The SLFP / SLPP was historically supported by working class Sinhala people. The UNP was supported by Tamils, Muslims and richer / more urban Sinhalas. In 2022, the SLPP collapsed due to an economic crisis and widespread corruption. The SJB was an attempt by a section of the UNP to win over former SLPP voters by adopting centre-left economic policies and Sinhala nationalist rhetoric. The UNP base - largely Tamil and Muslim - are not going to vote for them! This is why the JVP was able to win - they consolidated the working class Sinhala vote, while not threatening Tamils and Muslims.
Their voters just aren't using it, for some goddamn reason.
The reason being that, for many people, there is only one choice that is acceptable.

That's a viable path to getting your face in the public consciousness, so you can win next time. As you said, losing a prior election isn't a pre-requisite. But the posters you printed, the speeches you made, and the fact that one in thirty people took you seriously enough to vote for you, are a pretty strong boost when you run again.
Oh yea for sure, that I’m behind 100%. “Strategic voting” is just silencing your one chance to have a real voice based on whoever’s PR team is doing better.
I just read it as supporting third parties. I thought you were going to mention what happens if a third party were to get more votes but not a majority. I actually don't know. Would there still be a runoff between Dem and Rep or would the third party actually win it? I'd assume theres some rule that the third party has to win a majority or some bs
