Populist rhetoric – presenting arguments in people-centric, anti-elite and ‘good v. evil’ frames – is said to provide populist parties and candidates with an advantage in electoral competition. Yet, identifying the causal effect of populist rhetoric is complicated by its enmeshment with certain positions and issues. We implement a survey experiment in the UK (n≈9,000), in which hypothetical candidates with unknown policy positions randomly make (non-)populist arguments, taking different positions on various issues. Our findings show that, on average, populist arguments have a negative effect on voters’ evaluations of the candidate profiles and no effect on voters’ issue preferences. However, populist arguments sway voters’ issue preferences when made by a candidate profile that voters are inclined to support. Among voters with strong populist attitudes, populist arguments also do not dampen candidates’ electoral viability. These findings suggest that populist rhetoric is useful in convincing and mobilizing supporters but detrimental in expanding electoral support.
