On January 6, 2021, the belief that voter fraud was to blame for Trump’s 2020 loss led thousands of people to storm the Capitol during election certification, aiming to occupy it by force to stop this process. While only thousands participated, millions more voiced their support for the insurrection, and this begs the question: What explains perceptions of voter fraud and support for the January 6 insurrection? Recent studies establish that White conservatives are more likely to believe that voter fraud is a rampant problem, linking these perceptions to state efforts to expand access to voting systems where racial minority groups stand to gain equality. Using a combination of pre-election, post-election, and post-insurrection survey data, we examine the link between White racial attitudes and perceptions of voter fraud and views toward the insurrection. We argue that White racial attitudes are pivotal in explaining the perceptions of voter fraud that led to the January 6 insurrection. We find that White Americans with a bias for their own racial in-group over racial out-groups are likelier to doubt the election results after Donald Trump was declared the loser, though not before. We find these same attitudes are statistically associated with sympathy for the insurrection and insurrectionists.
