In 1964, Barry Goldwater lost the presidential election to Lyndon Johnson. At the time, most observers thought it was a “one-off.” Fifty-two years later, Donald Trump won the election. That, too, was judged a “one-off.” In this lecture, Sid Tarrow asserts that neither of these claims are true, but rather both Goldwater and Trump are part of a “long movement,” one that began in 1964.
