Are university still a left-wing thing in Europe? Unsure: HE is a hierarchical institution with egalitarian employees I find that universities increasingly inculcate selfish career concerns for status while leaving universalist concerns for global justice unchanged

🔍 Key feature: for the 2025 election, we've created our own crosswalks to handle municipality mergers and splits over time. 📈 This update allows for consistent longitudinal analysis of voting patterns, accounting for administrative boundary changes over the past 35 years.
