State Rep. Jenny Horne is running for Congress, challenging incumbent Republican Mark Sanford in the coastal 1st Congressional District. The Republican primary election is June 14. Horne is a Republican member of the South Carolina House of Representatives, representing District 94. She was first elected to the chamber in 2009.

Instead of seeking re-election, she is now seeking election to the U.S. House to represent the 1st Congressional District. Sanford currently serves the district after winning a special election in 2013. He previously represented the same district from 1995 to 2001, before being elected governor of South Carolina, a position he held from 2003 to 2011.
