Speedy Oteria Long was born in Tullos, Louisiana, in La Salle Parish on June 16, 1928. He was given the name Speedy because he was born prematurely.[3] He attended public schools in LaSalle and Winn Parish, graduating in 1945 from Winnfield High School. He served in the United States Navy from April 1946 to February 1948.[1]
Both of the Longs were segregationists but Gillis Long was less outspoken in his views than Speedy Long was, and Gillis had also, according to Speedy, aided the passage of the Civil Rights Act of 1964 by voting to increase the size of the House Rules Committee from 12 to 15 members, thus diluting the South's influence on the committee. Speedy used the slogan "Vote Against the Man Who Voted Against the South" in the campaign against Gillis. A state senator from New Orleans described the difference between the two Longs: Speedy was "a redneck" with a regional focus, while Gillis was "a cosmopolitan". In the primary, Speedy Long easily beat Gillis Long. Speedy's campaign in the general election was limited to a single 150-second television appearance. Although the Republican presidential candidate, Barry Goldwater, carried the district, Democrat Speedy Long won election handily, becoming the sixth member of the Long family to serve in the United States Congress.[2]
Long served in the 89th (1965–1967), 90th (1967–1969), 91st (1969–1971), and 92nd (1971–1973) Congresses, but did not stand for re-election in 1972.[1]
From January 4, 1973, to January 3, 1985, Long was the district attorney for Louisiana's 28th Judicial District.[1]
