“…While this result might seem counter-intuitive, research on uncivil rhetoric by political elites suggests that candidates are not, themselves, penalized by their base when using such strategies (Herbst, 2010;Mutz, 2015)-even though elite incivility is associated with systemic-level consequences such as reducing policy support, political trust, and out-party favorability (Goovaerts & Marien, 2020;Mutz, 2015;Otto et al, 2020). While we're not focusing on candidate incivility in this paper, the heated tone of Trump's rhetoric in the campaign has been documented by scholars as an outlier in contemporary political discourse (Mercieca, 2019;Stromer-Galley, 2019a). Considering the centrality of immigration to Trump's campaign and the evidence that his rhetoric became more heated than his opponents', it is possible that Trump's base did not penalize his negative campaigning strategies-or, at least, was more tolerant of them, as it is typically the case for challengers (Fridkin & Kenney, 2011).…”
