This is the electoral history of Ronald Reagan. Reagan, a Republican, served as the 40th President of the United States (1981–89) and earlier as the 33rd Governor of California (1967–75). Having been elected twice to the presidency, Reagan reshaped the Republican party, led the modern conservative movement, and altered the political dynamic of the United States. His 1980 presidential campaign stressed some of his fundamental principles: lower taxes to stimulate the economy, less government interference in people's lives, states' rights, and a strong national defense.
