This study investigates the perceived importance of regional partnerships and the extent of electoral interference by major powers in Czechia, Poland, and Slovakia. Grounded in Bauman’s liquid modernity, which emphasizes fluidity, instability, and fragmentation in modern societies, it explores how socio-demographic characteristics and political party preferences influence these perceptions. Using a comprehensive survey conducted by a professional agency, our unique data set includes responses from 3075 participants across the three countries. Regression analysis reveals that age and education significantly affect perceived partnership importance, while sex shows minimal variation. The study also identifies political parties with high and low odds of perceived electoral interference by major powers such as China, Russia, Germany, the United States and the European Union. The findings underscore the complexity of public opinion on foreign influence and the necessity for enhanced digital literacy to mitigate vulnerabilities in democratic processes. This research provides valuable insights for policymakers and experts in security.
