The Big Lie that Joseph Biden did not legitimately win the presidency in 2020 has mutated into a forward-looking belief among many Republicans that American democracy more generally no longer functions fairly. In the minds of the most ardent believers, political opponents — Democrats — must be stopped by any means necessary, including the sort of violence unleashed at the U.S. Capitol on January 6, 2021. Social media companies have promised to protect the upcoming midterm elections from mis- and disinformation, but their flawed policies and inconsistent enforcement result in the continued amplification of election denialism, especially in key battleground states, like Arizona, Michigan, and Pennsylvania.
