This article examines reactions to the Christian nationalist imagery and rhetoric employed during the January 6th, 2021 riot at the U.S. Capitol. We find evidence of both religious and partisan backlash among people who recalled evidence of Christian nationalism displayed by the January 6th rioters. Among Independents and Republicans who recalled religious symbols on January 6th, their overall religiosity declined. We also find that January 6th led not only to religious backlash but also partisan backlash—generally lessening favorability toward Donald Trump and Republicans and even leading Republicans to change their party identification.
