So how did Lula come from behind to defeat Bolsonaro? In short, turnout. Bolsonaro's vote share barely moved. But Lula banked millions of votes from those who didn't vote in the first round & won eliminated candidates' votes. A remarkable mobilisation. Second round turnout is usually below first.

Our broader takeaway: legitimacy judgments depend not only on citizens’ own preferences, but also on what they believe other people want. That creates vulnerability when those beliefs are wrong—but also a corrective possibility: accurate public-opinion information can shift legitimacy judgments.

This is part of our DFG project on false consensus beliefs in politics. Previously, we showed that false consensus beliefs are associated with stronger populist attitudes: doi.org/10.1111/pops... The new paper adds causal evidence that public-opinion information can shape legitimacy judgments.

But that relationship is observational. So we also experimentally provided accurate polling information showing that the proposals lacked majority support. The result: legitimacy ratings declined—modestly, but consistently.

Importantly, the effect was stronger when the polling information contradicted respondents’ prior beliefs (as preregistered): 👉 those who had initially perceived relatively high public support showed the largest decline in legitimacy ratings when shown that support was actually low.

First finding: many respondents overestimate how popular these minority-backed proposals are—especially those who support them themselves. More generally, supporters perceive substantially more public support than opponents do—consistent with the false consensus effect.

Second: perceived public support is associated with perceived legitimacy even after accounting for respondents’ own policy positions. People who believe that a proposal enjoys broader public support also tend to regard adopting it as more legitimate.

Previous research shows that majority cues can shape legitimacy judgments, but mostly using experimentally assigned cues in hypothetical scenarios. We ask whether citizens’ own beliefs about public opinion matter when evaluating salient real-world policy decisions.

We study four salient policy proposals in Germany. Respondents reported: • their own position • how much public support they thought each proposal had • how legitimate they would consider its adoption For two proposals, they received accurate polling information before assessing legitimacy.

Cool research note (says the handling editor)! “Don’t know” responses to left–right self-placement vary sharply by survey mode in the Eurobarometer. Broader lessons: (1) Be careful when comparing nonresponse across modes. (2) Making “don’t know” equally available and salient across modes is hard.

🎉 Happy to share that our new paper, "Do They Really Not Know? Survey Mode and Left-Right Self-Placement Responses," is out in @pvs-journal.bsky.social! 💡 Together with @hudde.bsky.social, I investigated how survey mode is associated with left-right self-placement. 🧵👇

Our AK Wahlen special issue on the 2025 German election closes with another excellent article: Krause, Thomeczek & Wagner find that small polling shifts around the 5% threshold influenced support for The Left and BSW.

Why do green parties struggle electorally despite widespread support for climate action? My new (first 😱) paper explores why green parties remain uniquely challenged in economic crisis & that the mechanism is not only about sociotropic concerns, but also voters’ pocketbooks 🧵 doi.org/10.1017/S147...

The Swiss People’s Party SVP is one of the oldest and electorally strongest radical-right parties in the world. But: electoral popularity ≠ policy popularity Voters keep supporting the SVP in elections, but only 2 out of 12 popular initiatives launched by the SVP have passed Data: Swissvotes

Reto Mitteregger@indubioproreto.bsky.social

A lot of European countries have seen the far-right winning in recent elections. Yet, the Swiss far-right SVP has just suffered its third consecutive direct democratic loss today: Its "neutrality-initiative" got massively rejected with only 29% yes votes.

⏳ Why are voters out of step with parties on immigration and redistribution? Hironao Yoda and Serika Atsumi study 16 Western European countries: newer cohorts link the two issues as parties do — older ones don't, so the gap should narrow with generational turnover. 🔗 doi.org/10.1080/0140...

Interesting new paper in @wepsocial.bsky.social by Yoda&Atsumi showing that "the positive association between pro-redistribution and pro-immigration attitudes is weaker among earlier cohorts." In other words: the number of left-authoritarian voters decreases across generations.

Ähnliche Muster auch sich in Mecklenburg-Vorpommern. Ein höherer AfD-Stimmenanteil korreliert stark mit Ländlichkeit und peripherer Lage. In Gemeinden mit geringerem Bevölkerungsverlust, höherer Beschäftigungsquote Älterer und höherem Einkommensteueraufkommen pro Kopf ist die AfD eher schwächer.

Julius Kölzer@juliusk.bsky.social

Saxony-Anhalt went to the polls, with the AfD falling just short of a majority. Here are some takeaways based on the preliminary results across all 218 municipalities and local socioeconomic characteristics. A thread 🧵(1 /n) Full analysis + write-up: juliuskoelzer.de/saxony-anhal...

Die AfD hat bei den Landtagswahlen 2026 ihre Ergebnisse gegenüber dem jeweiligen Landesergebnis bei der Bundestagswahl 2025 gar nicht mal so stark steigern können (wie man vielleicht denken könnte, wenn man immer nur den Vergleich zur vorherigen Landtagswahl sieht).

This Sunday, Die Linke could become Berlin’s strongest party for the first time. Importantly, its success in urban centers reflects a broader sociostructural transformation: from a party rooted in the support of production workers to one drawing disproportionate support from the new middle class.

Julius Kölzer@juliusk.bsky.social

Die Linke pulled off a surprise win in Germany’s most recent federal election and has suddenly become one of the most closely watched parties in Europe’s progressive politics. Behind the success lies a continuing structural transformation of its geographic support base. A short thread🧵
