Ronald Wilson Reagan (/ˈreɪɡən/; February 6, 1911 – June 5, 2004) was an American politician who served as the 40th president of the United States from 1981 to 1989 and became a highly influential voice of modern conservatism. Reagan faced former vice president Walter Mondale when he ran for re-election in 1984 and defeated him, winning the most electoral votes of any U.S. president, 525, or 97.6% of the 538 votes in the Electoral College. While he was in the service, Reagan obtained a film reel depicting the liberation of the Auschwitz concentration camp; he held on to it, believing that doubts would someday arise as to whether the Holocaust had occurred. After the campaign, Reagan remained in the public debate with the Ronald Reagan Radio Commentary series and his political action committee, Citizens for the Republic, which was later revived in Alexandria, Virginia, in 2009 by the Reagan biographer Craig Shirley.
