Donald Trump's campaign slogan to “Make America Great Again” captivated the imagination of millions of Americans by contextualizing disparate sources of social resentment as emblematic of a broader story of American decline. Employing a “traditionalist civil religious jeremiad,” Trump called for a reassertion of American exceptionalism, and extolled a romanticized golden age predating transformative social changes (e.g., sexuality, gender roles, racial equality). As such, his rhetoric legitimized the defense of white male privilege as a vital component of this restoration. While this use of civil religious themes emboldened those who harbor prejudicial views, it alienated others who interpret such rhetoric as an assault on the soul of the nation. Relying on a unique module within the 2018 Cooperative Congressional Election Study, we demonstrate that adherence to the tenets of American civil religion significantly exacerbated the effects of symbolic racism and modern sexism on support for Trump.
