South Carolina's 3rd congressional district

South Carolina's 3rd congressional district is a congressional district in western South Carolina bordering both Georgia and North Carolina. It includes all of Abbeville, Anderson, Edgefield, Greenwood, Laurens, McCormick, Oconee, Pickens, and Saluda counties and portions of Greenville and Newberry counties. The district is mostly rural, but much of the economy revolves around the manufacturing centers of Anderson and Greenwood. With a Cook Partisan Voting Index rating of R+21, it is the most Republican district in South Carolina.

History
Historically, the district was a Democratic stronghold, and Democrats continued to hold most local offices well into the 1990s. However, most residents share the socially conservative views of their counterparts in the 4th district and the district has elected Republicans since 1994. Republicans now dominate the district's politics at all levels, usually scoring margins rivaling those in the 4th. Indeed, no Democrat has cleared the 40 percent mark in the district in almost a quarter-century.

South Carolina's senior Senator, Lindsey Graham, held this seat from 1995 to 2003. He was succeeded by J. Gresham Barrett, who gave up the seat in order to run for governor. State Rep. Jeff Duncan won the seat in 2010.

From 2003 to 2013, the district included all of Abbeville, Anderson, Edgefield, Greenwood, McCormick, Oconee, Pickens and Saluda counties and most of Aiken and Laurens counties.
