PBS NewsHour celebrated the return of the ancient “October Surprise” election conspiracy theory -- the unsubstantiated rumor that Ronald Reagan’s 1980 presidential campaign, led by William Casey, delayed the release of the 52 American hostages in Iran in order to win election over Democrat Jimmy Carter. The original version was advanced by former Carter aide Gary Sick before being discredited in both follow-up news accounts and subsequent congressional hearings, which found the accusers shady and lacking in credibility.
