Off to this year’s #ecprgc25 in Thessaloniki. Together with Tapio Raunio and our panel chairs, we’ve organized a section with five panels on presidency research. If you’re attending, you’re very welcome! tinyurl.com/3wv6amme

Does cohabitation weaken presidents? Our global study (1850–2022), now out in International Political Science Review, finds it does – but only in semi-presidential systems and under a broader definition of cohabitation. P

Social trust and crises. Ali Abdelzadeh and T. Sedelius @sedelius.bsky.social examine the dynamics of social trust and its interaction with different fears during the COVID-19 pandemic, using a three-wave longitudinal dataset from Sweden (2020-2022). See the full article at doi.org/10.1111/1467...

⏳📢Cfp to the @ecpr GC in Thessaloniki Aug 2025. Deadline Jan 6. Consider a proposal to our Section on ”Presidential Politics and Security Threats: Institutions, Powers, and Policy” Welcome!

Interested in presidency research? Consider joining our @ecpr.bsky.social Standing Group on Presidential Politics.

My new article w/t C. Anckar: Does the president's power decrease during cohabitation (where the president and PM represent different camps)? Our results show that power decreases, but only where the president is directly elected and where we apply the broader of our definitions of cohabitation.

Weak autocracies are far more common than strong autocracies.

They are also often far more dangerous and damaging than strong autocracies.

Never take hope from an autocrat’s weakness. Instead, prepare for the worst.
