Allan Lichtman, the history professor who correctly predicted nine of the last 11 presidential elections, said he's received death threats after wrongly predicting 2024's results.Lichtman predicted a win for Vice President Kamala Harris over her opponent, former President Donald Trump, in September. "We've faced death threats, doxxing, swatting and intimidation at our doorstep. We will not be bullied. Federal law enforcement is now alerted," he wrote in an X post on Saturday.In a statement to BI, the American University professor said that the threats came through email and social media."There were two attempts to breach our home," Lichtman told BI.Lichtman said that no one had been hurt, adding that the police had responded to the break-in attempts.Representatives for the Washington, DC Metropolitan Police Department did not immediately respond to a request for comment from Business Insider.In a podcast uploaded to his YouTube channel on Friday, Lichtman said he thought the hate mail he was getting from the wrong prediction was "vulgar" and "mindless.""I admit I was wrong. I called a Harris win and she didn't win," he said on the YouTube stream."But I was far, far from the only forecaster to be wrong. Most other models were wrong," Lichtman added.Lichtman's "Keys to the White House" prediction model consists of 13 true-or-false questions. He said in a September interview with The New York Times that eight of the 13 keys were in Harris' favor.In 2016, he correctly predicted that Trump would win the election.The Republican candidate cruised to victory last week, clinching his second term in office with 312 electoral votes against Harris' 226.
