In 1947, the Supreme Court ruled in Elmore v. Rice that the white primary was unconstitutional and later ruled that segregation of the public schools was also unconstitutional (Brown v. Board of Education) . South Carolina’s Senator Strom Thurmond continued to lead resistance to recognizing the rights of African Americans. Thurmond opposed implementation of the Brown ruling by writing the Southern Manifesto condemning the Brown decision and encouraging resistance to desegregation. Senator Thurmond holds the record of twenty-four hours and eighteen minutes for his filibuster against the passage of a civil rights act that would provide some federal protection for the right to vote (1957).
As Democratic presidents John F. Kennedy and Lyndon Johnson responded to the Civil Rights Movement with support for the passage of the Civil Rights Act of 1964 and the Voting Rights Act of 1965, southern Democrats, most notably Strom Thurmond, withdrew their support for the president and the Democratic Party. Thurmond changed his party affiliation from Democrat to Republican (1964). South Carolina has voted for the Republican presidential candidate since 1964 with only one exception in 1976 when Georgia’s Jimmy Carter carried the state. Republican candidate Richard Nixon was supported by Thurmond in the 1968 election. He won further support with his ‘southern strategy’ of resisting the expansion of civil rights protections and thus appealing to southern voters. Ronald Reagan appealed to South Carolinians because of his stand on taxes and the Cold War.
