From 1895 to 1973, when the state constitution was amended to provide forhome rule in the counties, the counties had limited powers, under what was called "county purpose doctrine."[22] Essentially the General Assembly governed the counties through their state legislative delegations and, with one state senator per county, the state senator was particularly powerful. In the 1940s, Charleston County adopted acouncil-manager form of county government to better handle its needs.[23] In 1975 the state's Home Rule Act established a larger role for the county governments.
Charleston County has a large geographic area represented by a nine-member county council. From the turn of the 20th century into the 1960s, most African Americans were excluded from voting by the state'sdisenfranchising constitution and discriminatory practices. This gradually changed after passage of the federalVoting Rights Act of 1965.
Since 1969, members of the county commission have been elected in a modifiedat-large system for nine seats from four residency districts. Elections are held every two years for staggered four-year terms. Three Council seats are reserved for residents of the City of Charleston, three for residents of North Charleston, two for residents ofWest Ashley, and one for residents of East Cooper.[24][25] The council elects a chairman from its members for a limited term of two years, but chairs can be re-elected.
Charleston County was "one of only three counties in South Carolina to elect its entire county councilat-large. It was "the only county with a majority white population to do so."[24] At-large positions favor candidates who can attract a majority of the votes, reducing representation from smaller portions of the population, or geographic areas.
In 1989 county residents proposed a referendum to change representation on the county council to election fromsingle-member districts, which would have provided more opportunity for the sizable minority to elect candidates of their choice. This proposal was narrowly defeated in what both the county and the US government later defined as a racially polarized election. It was supported by 98% of the African-American minority voters; 75% of the white-majority voters rejected the referendum.[25] In practice, the at-large system results in the dilution of votes of the significant minority of African-American voters, who comprise more than one-third of the electorate. In practice, the minority voters have been unable to elect a candidate of their choice in all but a few elections in the three decades since the system was established.[25]
In January 2001, the US Department of Justice filed suit against the county government for racial discrimination based on theat-large system, which the suit contended violates Sec.2 of theVoting Rights Act of 1965 by diluting voting power.[26] The department had tried to negotiate with the county over changes in November 2000. Four voters independently filed suit as plaintiffs against the county on the same basis, and the District Court combined the cases. Justice officials noted that the at-large seats dilute the voting strength of the African-American minority in the county, who in 2000 comprised 34.5% of the population. In all but a few cases over three decades, they have been unable to elect candidates of their choice to the county commission. Whites (European Americans) comprise 61.9 percent of the population in the county.[21] Since the late 20th century, the white majority has electedRepublican Party candidates.
The DOJ officials noted that the voting preference issue is not just a question of ethnicity; voters in black precincts in the county had rejected a Republican African American as a candidate for the council; they supported theDemocratic at-large candidate. The suit noted that historically, black and white precincts in Charleston County have consistently supported different candidates for the council. It noted that, because of the white majority and the large geographic area, which increases costs for campaigning, "white bloc voting usually results in the defeat of candidates who are preferred by black voters."[26] DOJ noted that blacks lived in compact areas of the county, were cohesive in voting, and could comprise the majority in three districts if the county seats were apportioned as nine single-member districts. They could vote and gain representation proportional to their part of the citizenry.[26]
InUnited States v. Charleston County, SC (March 2003), the District Court ruled that Charleston County improperly diluted the voting strength of African-American voters "by maintaining an at-large voting system in a manner which violated Section 2." It enjoined the county from using that system, noting that the "Order is radically not a condemnation of the citizenry of Charleston County but rather a recognition that the specific bulwark of an at-large system, in twisted concert with the particular geographic and historical realities of this County, unlawfully and institutionally inhibit a community of voters in Charleston County from equal access to the electoral process."[27]
The county appealed. In July 2003, the 4th Circuit Appeals Court found that historic voting in the county was racially polarized and that minority candidates had mostly not been successful in seeking office, two conditions that are recognized under the law as showing discriminatory effects of the voting system in the county.[25] As of July of that year, the 4th Circuit Court affirmed the District Court's ruling,[28] and on April 29, 2004, issued its written decision affirming the District Court.[24] Based on historical and economic analysis, the courts found that race was a more important issue than partisanship in influencing the outcome of the elections.[24] The county appealed to the US Supreme Court, and acertiorari was denied in November 2004.[29]
The County Council system was changed in 2004 to elect individuals from nine single-member districts, with members serving four-year staggered terms. As of January 2015, elected members of the council include 4 White Republicans, 2 White Democrats and 3 African-American Democrats.[30] Republican Elliott Summey was elected by council members as chairman, replacing Democrat Teddie Pryor, who had served for six years. Summey had served as his vice-chair for five years. Pryor was first elected to the council in 2004. Summey was first elected in 2008.[31]
Charleston County is split betweenSouth Carolina's 1st congressional district, represented byRepublicanNancy Mace, andSouth Carolina's 6th congressional district, represented by DemocratJim Clyburn.[32]
A largely urban area containing the cities ofCharleston andNorth Charleston, Charleston County is a reliable, but not overwhelming, supporter of theDemocratic Party in the 21st century. In2020, it voted forJoe Biden by nearly 13 points, the best Democratic performance in the county since1944 and over 20 points more Democratic than the state as a whole. No Republican presidential candidate has won the county in over two decades as of 2025.
