Existing studies suggest that what people do and do not think of as being ‘politics’, varies a lot. Some citizens embrace narrow understandings, regarding only few issues as ‘political’. While others hold broad conceptions. What remains unclear is to what extent citizens agree on the contents, i.e., which topics are ‘political’. Using representative survey data from the U.S. (N = 1000), this article illustrates the overlaps and differences in conceptions of politics that different groups of citizens hold. Specifically, the results of a cluster analysis reveal five groups. The citizens within each group share similar conceptions of politics, while across groups conceptions differ. We find one group considering everything as political, one not regarding anything as such, and a third one identifying only tax-cuts as ‘political’. In between these extremes, two groups identify politics in terms of rather demarcated spheres of issues: domestic, or cross-border/global issues. Further analyses point to important differences in the groups’ socio-demographic profiles, political interest, and political behaviors. This shows, in their minds, people draw boundaries around politics in quite varied, yet principled, ways. This comes with a meaningful diversity in citizens’ connection to the political world around them, and with important implications for their roles within it.
