Really excited to see my final dissertation paper out 🎉

Do parties shift their issue priorities when polls decline?

Looking at press releases from 68 parties in 9 countries, we find little evidence that they do.

American Journal of Political Science | MPSA Journal | Wiley Online Library Concern that immigration worsens crime problems is prevalent across Western publics. How does it shape electoral politics? Prior research asserted a growing left–right divide in immigration attitudes...

Glad to see this out at @ajpseditor.bsky.social! I show that the immigration-crime issue, when salient, can shift leftist cosmopolitans to the Right. This is due to leftist voters being more conservative on crime than leftist parties.

In the top affiliations, we see some changes with Gothenburg gaining momentum, and the LSE losing its first place from last year. Happy to see Humboldt making it into the top 10!

(All figures are based on the number of (co-)authorships.)
