 The twenty years from 1948 to 1968 were a highly transitional time for the politics of South Carolina & Williamsburg County, largely in part due to the Democratic Party's increasing support for African-American civil rights & enfranchisement.Dixiecrats managed to carry the county twice, while Republicans managed to carry the county three times in this timespan, while increased black registration led to Democrat Hubert Humphrey winning the county in 1968.Since 1968, the majority African-American county has only backed a Republican once in 1972, when Richard Nixon won the county as he swept every county statewide in the midst of a 49-state national landslide.
