 York County is by far the largest county in the district, with almost one-third of its population, and its Republican bent has pushed the district as a whole into the Republican column in recent years.In November 2010, the Republican Mick Mulvaney defeated longtime Congressman John Spratt and became the first Republican since Robert Smalls and the end of Reconstruction to represent the district.Following Mulvaney's confirmation as the Director of the Office of Management and Budget, a special election was held in 2017 to determine his successor.
