This chapter makes the case for increased attention to the discourse theoretical notion of sedimented practices in populism research and International Relations (IR). Sedimented practices circumscribe the domain of credibility and intelligibility of a society’s socio-economic setting. In contrast to previous studies in both populism research and IR that stress US President Donald J. Trump’s radical break with traditional foreign policy during both his first and second terms, a focus on sedimented practices shifts our attention to the need for any successful project to resonate with established discursive patterns to gain credibility. We illustrate the theoretical argument drawing on examples from Trump’s campaign statements on foreign policy since 2015. We argue that the notion of sedimented practices helps tease out how even Trump’s foreign policy vision draws on deeply established traditions of US foreign policy for legitimacy.
