The United States presidential election of 1980 featured a contest between incumbent Democrat Jimmy Carter and his Republican opponent, Ronald Reagan, as well as Republican Congressman John B. Anderson, who ran as an independent. Reagan, aided by the Iran hostage crisis and a worsening economy at home, won the election in a landslide.
Carter, after defeating Ted Kennedy for the Democratic nomination, attacked Reagan as a dangerous right-wing radical. For his part, Reagan, the former Governor of California, repeatedly ridiculed Carter, and won a decisive victory; in the simultaneous Congressional elections, Republicans won control of the United States Senate for the first time in 28 years. This election marked the beginning of what is popularly called the "Reagan Revolution."
