2020 South Carolina House Election Interactive Map

All US House seats to be contested in 2020

South Carolina has seven congressional districts. Republicans hold a 5-2 edge after Democrats flipped the 1st district in 2018. That will be a closely-watched race in 2020; none of the others seats are competitive.

Redistricting will occur in 2021 after the 2020 Census. While South Carolina is expected to maintain its 7 congressional districts, expect some changes to the district boundaries that will be effective with the 2022 election.
