Manipulating the masses? Right-wing populist messages, political ideology, and public support for multilateral development aid in Germany, the United States, and the United Kingdom

How does right-wing populism affect public preferences for foreign development aid spending across the liberal/conservative ideological spectrum? This research examines the complex interplay between exposure to right-wing populist messages targeting aid and political ideology at the mass level in Germany, the United States (U.S.), and the United Kingdom (UK) with data from original survey experiments. First, the experiments indicate that populist rhetoric reduces public support for foreign aid across all countries albeit to varying degrees. Second, the moderating role of political ideology is variable and complex across the different countries. In Germany, populist anti-aid messages reduce support among voters on the center of the ideological spectrum and among those without clear ideological preferences. In the U.S., anti-aid messages affect those on the left. In the UK, the effect of populist anti-aid rhetoric surprisingly does not vary cross ideological groups. Our results have implications for the prospects of public support for development cooperation in the shadow of populism.
