Contributing to burgeoning studies of populism, this article conceptualises and contextualises Trump’s language as ‘Jacksonian populism’. We explore how this style of populist discourse influenced political debates before and after Trump’s election. Ours is the first article to analyse opposition and media responses to Trump’s construction of ‘real America’ as that of a Jacksonian, White, and male working class. To do so, the article analyses 1165 texts, from the government, opposition, newspapers, television coverage, and social media. In addition to locating Trump’s reification of a mythologised White working class within a broader Jacksonian tradition, we find that the Democratic opposition and mainstream media initially reproduced this construction, furthering Trump’s cause. Even where discursive challenges were subsequently developed, they often served to reproduce a distinct – and hitherto unspoken for – White (male) working-class America. In short, early resistance actively reinforced Trump’s discursive hegemony, which centred on reclaiming the primacy of working, White America in the national identity.
