How Many Presidents Have Been Accused of Being the Antichrist?

Hint: It’s not just Obama.

Suspected White House shooter Oscar Ramiro Ortega-Hernandez was obsessed with President Barack Obama, according to investigators, and reportedly thought Obama was the Antichrist. In September, heckler David Serrano called Obama “the Antichrist” at a fundraiser. Have other U.S. presidents been suspected of being the Antichrist?

Yes. Perhaps the first U.S. president suspected of being the Antichrist was Franklin Delano Roosevelt. Roosevelt’s extraordinary influence and desire to form a worldwide United Nations raised the suspicions of many conservative Christians. When President Roosevelt began to engage in diplomacy with the Soviet Union, prominent evangelist and politician Gerald Burton Winrod suggested that Roosevelt was at the very least under the influence of the Antichrist, and carrying out his plans. During John F. Kennedy’s candidacy for president, Protestant leaders compared electing Kennedy, a Catholic, to electing the Antichrist. In 1990 a man named Gregory Stuart Gordon invaded the house of former president Ronald Reagan, telling Secret Service agents “Ronald Reagan is the Antichrist. He must be killed and I must kill him.” While Gordon’s attorney claimed that Gordon was only trying to attract attention in hopes of gaining treatment for a drug problem, courts judged that his threat was serious and sentenced him to a two-year prison term.
