George Corley Wallace Jr.
Title: George Wallace
Passage: George Corley Wallace Jr. (August 25, 1919 – September 13, 1998) was an American politician and the 45th Governor of Alabama, having served two nonconsecutive terms and two consecutive terms as a Democrat: 1963–1967, 1971–1979 and 1983–1987.  Wallace has the third longest gubernatorial tenure in post-Constitutional U.S. history, at 16 years and four days.  He was a U.S. Presidential candidate for four consecutive elections, in which he sought the Democratic Party nomination in 1964, 1972, and 1976, and was the American Independent Party candidate in the 1968 presidential election.  He remains the last third-party candidate to receive pledged electoral college votes from any state.
Title: Asa Earl Carter
Passage: Asa Earl Carter (September 4, 1925 – June 7, 1979) was a 1950s Ku Klux Klan leader, segregationist speech writer, and later western novelist.  He co-wrote George Wallace's well-known pro-segregation line of 1963, "Segregation now, segregation tomorrow, segregation forever", and ran in the Democratic primary for governor of Alabama on a segregationist ticket.  Years later, under the alias of supposedly Cherokee writer Forrest Carter, he wrote "" (1972), a Western novel that led to a 1976 National Film Registry film, and "The Education of Little Tree" (1976), a best-selling, award-winning book which was marketed as a memoir but which turned out to be fiction.
Title: George Wallace presidential campaign, 1968
Passage: Former Governor of Alabama George Wallace ran in the 1968 United States presidential election as the candidate for the American Independent Party.  Wallace's pro-segregation policies during his term as Governor of Alabama were rejected by the mainstream of the Democratic Party.  The impact of the Wallace campaign was substantial, winning the electoral votes of several states in the Deep South.  Although Wallace did not expect to win the election, his strategy was to prevent either major party candidate from winning a majority in the Electoral College.  This would throw the election into the House of Representatives, where Wallace would have bargaining power sufficient enough to determine, or at least strongly influence, the selection of a winner.
