Nah, just vote for the party you like the most. The nerds at the elections office take care of the math themselves. "Better" than US/UK/Canada where you have to consider a primary system or multiple elections or "Liberal Democrats win here" signs to not split the vote.

You absolutely don't. The formula they give for calculating seats from votes is very simple and only uses a few letters from the standard alphabet.

The section further with the complicated Greek formulae is for a different voting system, explicitly not the Icelandic one.

That didn't really make sense. On the one hand, the author complains that proportional elections favor a limited number of parties, which don't always give voters good options to choose from. And on the other hand, the winner usually doesn't get the majority of seats, forcing them to negotiate with other parties instead of governing unilaterally.

Then there the focus on the left vs. the right, which is no longer as relevant as it used to be during the cold war. If you choose a single faction (such as the left, conservatives, or environmentalists), that specific faction is almost always smaller than everyone else combined. When there are multiple major issues instead of a single overarching question, political divisions become more nuanced than simple X vs. not-X.

If your source for "Dutch levels of weirdness" is just that article, then keep in mind that the VVD being "in power" meant that they were one of the parties in the government coalition. They have had to compromise with other parties through all of that time, and so it was not the case that those governments were only representative of a very small party of the electorate, as that article makes it sound.

(In my opinion, the Dutch system is one of the best implemented in practice, precisely because of its proportionality.)

The two main parties in the US are way too happy with the status for any change to happen. If there is one thing they hate more than each other it's another party.

There was a time when senators were not elected by popular vote. The constitution leaves a lot of this up to the states and just by convention they mostly do the same thing.

> Huh, TIL the Constitution doesn’t require Congressional districts.

True, but...

> A state could technically switch to a model like this for assigning representatives at large.

No, it can't because Congress itself is given the overriding power in the Constitution to regulate the "time, place, and manner" of elections to the House, and has exercised it to prohibit at-large districts (many times, with lax enforcement, but the most recent mandate, adopted in 1967, has not had the compliance problems the earlier ones often did.) The 1967 mandate was adopted under the dual specter of a some states failing to resolve districting controversies and potentially facing judicially-imposed at-large districts and several states having used at-large districts for non-federal elections to effectively disenfranchise Black voters and concerns that the same might be done to Congressional delegations as a way of blunting the impacts of new rules like the Voting Rights Act.

There is a federal law.

There has been numerous proposals in the Congress to get rid of it, but they don't get ratified because two parties like the status quo.

People will have to make it an issue.

> It's interesting that it's possible to achieve proportional representation with respect to geographic distribution and party votes simultaneously.

That would be interesting, but it's not even possible to achieve one of those things by itself.

It is possible! But with more than two dimensions, you have to allow deviations from perfect proportionality to guarantee a solution exists. The more dimensions, the worse it gets, until eventually proportionality breaks down entirely. [1] defines a method to do this and simulates the results on an election where district and party seats are distributed proportionally and divvied up by gender proportionally. The result is a better national proportionality at the expense of worse local proportionality.

> So the entire system is biased away from local representation and towards party policy decided on a national basis.

> That policy is in turn heavily weighed towards the interests of geographic areas

Forgive me if I'm missing something, but these sound like contradictory claims to me?

As an American, I feel I'd prefer this system. The number of members of each party that make it to Congress is the main determinant of what policy gets passed. But I can only influence that indirectly, by choosing which party represents my local district. If I'm in a solid minority in the district I live in, I basically have 0 influence on the result of the election. Overall, those invisible lines let politicians crack and pack constituencies so a party with a minority of the votes still gets a majority of the seats.

In this system, the number of representatives of each party would be determined by the national popular vote, meaning I can more directly vote for which party gets the majority. Your vote does two things: it casts a vote for your party against the other parties in gaining them seats, and it casts a vote for your favorite party candidate over other candidates in the party (including those in other districts) to determine which candidates of the party earn the seats the party is given. It reduces the effect of the invisible line in weakening my vote. I'm okay with this meaning that sometimes my vote helps elect someone in a different district, since this would mean my district doesn't have enough members of my party to justify a representative of our own and because a lot of times the lines are arbitrary anyway. It would require bigger districts with multiple winners, and sometimes that the person with the 6th or 7th most votes in the district gets the 4th or 5th seat instead. This, in my mind, is the "gerrymandering correction:" it ensures those parties who were disadvantaged by the line drawing get their fair share of party members.

As for one vote counting twice as much as another, my understanding (and please correct me if I am wrong) is that the main cause of that is differences in turnout between the different districts and rounding representatives to the nearest whole number. Nothing can be done about the later (big problem in the US too -- people per district varies by hundreds of thousands of people, not to mention the disparity in the Senate). For the former, you could proportion representatives between districts based on turnout instead, but this is a bad idea since it makes it much harder to campaign in a district if you don't know how many seats are up for grabs.
