Happy to see our new paper on mainstream-to-challenger defection in print! w/ @denis-cohen.bsky.social & @aigneranna.bsky.social Check out Denis' summary below! Thanks to @nilssteiner.bsky.social, @conradziller.bsky.social & @ackermannk.bsky.social for organizing this SI! tinyurl.com/5aa9wrmb
First page of the journal article "From the center to the fringes: A comparative test of attitudinal explanations for mainstream-to-challenger defection" by Denis Cohen, Werner Krause, and Anna Aigner, published in Electoral Studies. The page shows the journal head, author affiliations at the University of Mannheim and the University of Potsdam, keywords, a link to the replication dataset, and the full abstract.Dot plot showing net balances of vote switching between mainstream and challenger parties, in percentage points, across 16 west European elections from 1973 to 2025. Each election is a point with a 95% credible interval, ordered left to right from most negative to most positive. Values run from about −6 to +15 points; positive values mean net gains for challengers. German elections are labeled individually and mostly sit between −4 and +4 points. Germany's February 2025 election, highlighted in red, is a clear outlier at nearly +10 points, placing it among the highest in the series alongside the Netherlands 2002, Greece 2012, Denmark 1973, and Italy 1992.

Whether or not radicalization is a good replacement, the political science concept of polarization is normatively dubious, descriptively thin and causally... eh, let's not even go there. I know you just got a big grant to study it but I'm sure they'll let you spend the money on something more useful

PhD successfully defended! "Beyond the Two-Party Divide" examines how affective polarization works in Europe, and when it matters for democracy. Short answer: Europe's multiparty systems have particularly good "safeguards" to prevent polarization from spiraling out of control like in the U.S.

Labour is desperately trying to appeal to Reform supporters. In October, we asked people in the UK if they perceive a party as a "party for someone like them". Only very few people say this for both Labour and Reform. The correlation is negative. Labour is chasing an electorate that does not exist.
