The European Political Science Review (EPSR) has published my solo-authored paper on Affinity Voting in Europe 🤓
In it, I ask:
Do voters prefer in-group politicians?
Answer:
Sometimes, sometimes not. Minorities prefer their in-group less often than majorities do.

First page of the article "Measuring issue salience for political parties using LLMs" by Kenneth Benoit and Michael Laver, published online first in West European Politics. Shows the title, authors, and abstract.
Box plots showing the distribution of 'budgeted' issue salience scores across six policy dimensions (economic, social, environment, EU, decentralization, immigration), comparing expert surveys, Manifesto Project codings, and LLM-based estimates.
🎉 Online first:
LLMs estimate party positions well. How about issue salience?
@kenbenoit.bsky.social and Michael Laver show its harder: salience is inherently relative and more implicit. LLM's salience estimates are usable but track experts less closely than positions.

Hope you like it! 🤞
Do citizens care who makes policy?
In Germany, some policies can be adopted either by federal or state governments. But do voters have preferences over which actor adopts a policy?
Turns out, they mostly do not.

Poster for the Summer 2026 joint lecture series “Democratic Challenges in Europe” organized by Baltic Peripeties / IFZO at the University of Greifswald. Features seven lectures between April and July 2026 on topics including affective polarization, democratic backsliding, migration, youth representation, the radical right, and ethnic domination.
This summer term, our joint lecture series at @baltic-peripeties.bsky.social and @ifzo.bsky.social returns with "Democratic Challenges in Europe".
For this term's programme, @oksanaalekseev.bsky.social and I invited 7 fantastic scholars to discuss democratic resilience, stability, and contestation.

Abstract of the article "A party's pledge fulfillment and procedural transparency affect voters' trust" by Ann-Kristin Kölln, published online first in West European Politics. Shows the title, author, and abstract summarising a survey experiment on how party performance cues shape trust.
Figure 2: point estimates of voters' trust in the party (scale 0–1) under three experimental conditions — control, good pledge fulfilment, and bad pledge fulfilment — with 95 percent confidence intervals. Trust is highest under good fulfilment (~0.52), intermediate under control (~0.48), and markedly lower under bad fulfilment (~0.36).
Figure 6: two line plots showing predicted effects of perceptions of a party's pledge fulfilment (left) and law compliance (right) on voters' trust (0–1), both measured on a 1–7 scale with 95 percent confidence ribbons. Trust rises steadily with perceived pledge fulfilment and law-compliance.
🎉 Online first:
What moves voters' trust in a political party?
@annkristinkolln.bsky.social's new study shows that a party's pledge record and its procedural transparency shift trust by 7–26 points — read by voters as signals of ability and integrity.

How does coalition participation influence party membership?@hannaeback.bsky.social @michaelimre.bsky.social and I find that junior coalition partners lose more members than parties that govern alone, and an increasing ideol. diversity within the cabinet is related to a decreasing number of members.

Very happy to see this out in @jeppjournal.bsky.social - radical left and right movements and parties alike increasingly define themselves around explicitly European identities - but with very different ideas of what "Europe" means: ⬇️
📢 New publication! 📢
So happy to see this paper finally out @epsrjournal.bsky.social !
Looking at public perceptions of party positions in 29 elections across 20 European countries, I test whether populist radical parties are seen as more moderate when they are part of a government coalition.

Happy that our article is now available online at JEPOP!
Using German data, @salvabarbaro.bsky.social, Maike Roth and me illustrate how voter preferences are translated into electoral outcomes, challenging common narratives about declining support for social democrats and rising right-wing support.
