The Joe Biden Is Dead Conspiracy Theory meme revolves around various internet rumors claiming the 46th President has been replaced by a body double, a clone, or a CGI hologram. These theories often highlight minute physical details, such as changes in ear shape, height, or gait, as 'undeniable proof' of a secret cover-up. While largely rooted in fringe political speculation, the meme has evolved into a satirical tool used by both believers and skeptics to poke fun at the absurdity of modern information warfare and the 'investigative' nature of online sleuths. It follows the long-standing tradition of 'replacement' myths, similar to the Paul is Dead or Avril Lavigne clone theories, adapted for the hyper-polarized digital age.
