As President Trump nears his first 100 days in office next week, I called the professor who predicted Trump’s win and has accurately forecast the outcome of every U.S. election since 1984 to ask him whether he still believes in his other famous forecast — that Trump will be impeached. Allan Lichtman, a distinguished professor of history at American University, had forecast that Trump would be impeached since months before last year’s elections, and has now published a book titled “The Case for Impeachment.” I was curious whether Trump’s latest policy reversals from some of his most outlandish populist stands will diminish the chance of an impeachment.
