Abstract When political theorists consider rhetoric, they are often concerned with exceptional, rather than everyday speech—affectively charged speech that is strategically manipulative or, conversely, speech that triggers judgment and imaginative thinking. What is missing is a framework that captures the political effects of far more mundane and commonplace forms of rhetoric: speech acts that do not stand out as exceptional, but which nonetheless have significant consequences. This chapter proposes the concept of “rhetorical resonance” and makes a case for attending to the iterative, constitutive effects of everyday rhetorical encounters. Building from the hermeneutic theory of Hans-Georg Gadamer, the chapter argues that rhetoric that “resonates” with discursive horizons can nevertheless transform those horizons, ushering in new conditions of political possibility. To illustrate the power of resonant rhetoric, the chapter considers the lead-up to the 2021 storming of the U.S. Capitol and the effects of repeated claims of election fraud and mismanagement.
