Guter Punkt. Es gibt sicher viele "echte" Gründe, warum Korrelationen auftreten dürfen (z. B. auch Größe von Wahlbezirken -> pos. Korrelation der Stimmen). Es geht um die Stärke des Zusammenhangs. Mir fallen keine "unverdächtigen" Gründe ein, warum der Anteil von BSW=0 100x so groß sein sollte.

Genau das hatte ich mir für eine grobe Schätzung angeschaut. Die Summe der BD-Zweitstimmen in Wahlbezirken mit BD>BSW ist 819, und die Summe der BSW-Stimmen dort 139. Die Differenz (als potenzieller Zugewinn) ist 680 - nur 7 Prozent der für die 5% fehlenden 9529 Stimmen.

Falls sich das jemand anschauen (auch ob ich auf die Schnelle keinen Fehler gemacht habe) oder das erweitern möchte, hier sind meine paar Zeilen Stata-Code. Ist vielleicht auch ein interessantes Beispiel für die Statistik-Lehre.

Auf der anderen Seite: Das betrifft sehr wenige Wahlbezirke. Wenn man es mal grob überschlägt, wird klar, dass das BSW (alleine) damit längst nicht auf die „fehlenden“ 9.529 Zweitstimmen kommt.

Das ist alles natürlich supersimpel, aber ich kann mir das nicht anders erklären als darüber, dass hier tatsächlich Fehlzuordnungen passiert sind.

In den 25 „besten“ Bündnis Deutschland-Wahlbezirken (>=15 Zweitstimmen) steigt der Anteil von Wahlbezirken mit Zweitstimmen-BSW=0 auf über 62,5% (15 von 24). Er ist also ca. 100-mal so groß wie über alle Wahlbezirke hinweg.

Das sind die betroffenen 15 Wahlbezirke:

Wenn wir uns nun die Verteilungen der BSW-Zweitstimmen getrennt für Wahlbezirke anschauen, in denen das Bündnis Deutschland laut Ergebnis außergewöhnlich stark war (vs. andere), sehen wir das folgende Bild.

Es ist insgesamt sehr selten (in 0,61% der Stimmbezirke), dass das BSW exakt 0 Zweitstimmen bekommen habt. (Auf der anderen Seite ist es relativ oft passiert (53,6%), dass das Bündnis Deutschland exakt 0 Zweitstimmen bekommen hat.)

Meine Grundannahme: In Abwesenheit von Fehlzuordnungen sollte der Anteil der Fälle, in denen das BSW laut Ergebnis gar keine Zweitstimmen bekommen hat, (weitestgehend) unabhängig davon sein, ob die Kleinstpartei Bündnis Deutschland in einem Wahlbezirk außergewöhnlich stark ist.

Ich war neugierig und wollte mir mal selbst anhand der Ergebnisse auf Wahlbezirksebene einen Eindruck von den vom BSW beklagten, vermeintlichen Fehlzuordnungen bei der Bundestagswahl 2025 verschaffen. 👇

"Captain Gains" on Capitol Hill
Shang-Jin Wei & Yifan Zhou
WORKING PAPER 34524
DOI 10.3386/w34524
ISSUE DATE November 2025
Using transaction-level data on US congressional stock trades, we find that lawmakers who later ascend to leadership positions perform similarly to matched peers beforehand but outperform them by 47 percentage points annually after ascension. Leaders' superior performance arises through two mechanisms. The political influence channel is reflected in higher returns when their party controls the chamber, sales of stocks preceding regulatory actions, and purchase of stocks whose firms receiving more government contracts and favorable party support on bills. The corporate access channel is reflected in stock trades that predict subsequent corporate news and greater returns on donor-owned or home-state firms.

(1/10) 🚨Preprint alert!🚨

In this article, I challenge claims of a generational rise of conservative men. In the media and recent academic publications, the so-called ‘youth gender gap’ has been interpreted as a generational phenomenon.

We study the role of generations in the urban-rural divide, which is increasingly shaping the politics of many democracies.

Studying Switzerland, we show: The urban-rural divide is stronger among younger generations. (1/10) 🧵👇

new paper by Sean Westwood:

With current technology, it is impossible to tell whether survey respondents are real or bots. Among other things, makes it easy for bad actors to manipulate outcomes. No good news here for the future of online-based survey research

Racial Resentment Among White Americans by Birth Year and Demographics

This figure presents the same four-panel layout (education, gender, geography, religion) but for White Americans from birth years 1940 to 2000.

Education panel: A pronounced divide shows non-college Whites with substantially higher resentment across all cohorts, increasing sharply for older birth years. College-educated Whites rise more modestly but remain distinctly lower, especially among younger cohorts.

Gender panel: Male and female trendlines rise together, with women slightly higher in mid-century cohorts. Younger cohorts of both genders start lower and climb with age.

Geography panel: Regional lines separate clearly: the South is highest in resentment, followed by the Midwest. The West and Northeast show lower levels, with the Northeast consistently at the bottom. All regions slope upward toward older cohorts.

Religion panel: Protestants show the highest resentment, peaking among mid-century cohorts. Catholics sit in the middle. Non-affiliated Whites show the lowest resentment, especially among younger respondents, with a small rise among mid-century generations.

The figure notes CES 2024 data with GAM-smoothed trendlines.

Those claiming Dems should retreat on racial justice aren't hard-headed realists, they're pushing against the electoral tide rather than leaning into it. The story of Gen Z isn't about racist backlash or red-pilled young men. It's the most racially progressive generation in American history. 🧵

Quick thread on the BBC and the political and societal significance of recent developments:

One of the main reasons the UK has historically been so much less polarised than the US, is that Britain has a shared source of information, consumed and trusted by most people regardless of their politics.
