In 2012, FairVote did a study on partisanship in the congressional districts, giving each a percentage ranking (D/R) based on the new 2012 maps and comparing that to the old 2010 maps. South Carolina's 3rd District partisan breakdown did not change because of redistricting.[6]

  • 2012: 32D / 68R
  • 2010: 32D / 68R
