In 1970, Campbell took a leading role opposing the racial integration of public schools in Greenville. He spoke to a crowd of thousands in front of Parker High School against integration, and on January 25 he led a motorcade of 800 vehicles to the
state capitol in Columbia to protest "forced busing" of students to integrated schools. Campbell served in the
South Carolina House of Representatives from 1970 to 1974 during the administration of Governor
John C. West, who defeated Republican nominee
Albert Watson, the choice of
U.S. Senator Strom Thurmond, in the
1970 South Carolina gubernatorial election. With
Lee Atwater as a key political strategist, he made an unsuccessful bid for
lieutenant governor in
1974 running to serve alongside Republican gubernatorial nominee
James B. Edwards of
Charleston. While Edwards was elected, Campbell lost to Democrat
Brantley Harvey; despite the loss Campbell would continue to seek Atwater's counsel throughout his career. From 1976 to 1978, during the Edwards administration, he served in the
South Carolina Senate. In between his two stints in the
General Assembly, he served as executive assistant to Governor Edwards. In
1978, Campbell won election to the
United States House of Representatives from the Greenville-based
South Carolina's 4th congressional district; he defeated Max M. Heller, the Democratic mayor of Greenville and an immigrant from
Austria, to fill the seat vacated by the retiring
James Mann. Campbell hence became the first Republican to hold the 4th district seat since
Reconstruction. Campbell served as state campaign chairman for
Ronald Reagan's
presidential campaign in 1980 and
1984, and as southern regional chairman for
George H. W. Bush's
presidential campaign in 1988. ==Governor of South Carolina (1987–1995)==
