This study illustrates how the emphasis structure of counterpublic discourses surfacing online can be predicted by that of the dominant publics that these counterpublics—at the argumentative level—so resolutely oppose. Deploying a single common case study design, the article scrutinizes a counterpublic discourse that surfaced in the comment sections of Germany’s opinion-leading news websites in the week after the surprising electoral success of a new anti-Euro party, the Alternative für Deutschland (AfD). Quantitative content analysis identifies 75% of all comments posted (N = 2955) to all articles about the AfD (N = 19) as part of an anti-Euro counterpublic. While this counterpublic sharply opposed the editorial lines of Germany’s unanimously pro-common-currency media, it still aligned its efforts closely with this dominant public—albeit at a deeper level. As the findings demonstrate, the frequencies with which commenters adopted six emphasis frames were significantly predicted by the frequencies of these frames in mainstream news.
