Many studies have shown that there is a positive relationship between education and political knowledge. However, some scholars have recently challenged this idea, arguing that the positive correlation between education and knowledge may disappear once confounding variables are considered. In this paper, we replicate a recent study that used the discordant twin design to examine the association between education and political knowledge. More specifically, we analyze the relationship between education and political knowledge within monozygotic (MZ) twin pairs, which enables us to bypass sources of confounding of the relationship (i.e. genes and socialization) because MZ twins reared together share both. Using data from a 2019 survey of twins from the Danish Twin Registry, we find that, consistent with earlier work, after accounting for familial factors, the relationship between education on political knowledge is small and not statistically significant.

Given the importance of issue competition in a West European context and the growing use of Facebook in elections, this paper studies how politicians use Facebook to shape the campaign agenda. We analyze the issues addressed in 6,388 Facebook posts by candidates in the Danish 2011 parliamentary election. A limited share of Facebook updates is dedicated to issues. The Facebook agenda did not respond to standings in the polls, nor to the media agenda or public agenda. Comparing issue engagement of new candidates and rerunning candidates we find that the Facebook campaign agenda is not simply politics as usual. [ABSTRACT FROM AUTHOR]
