Fourth District Congressman Bob Inglis of Travelers Rest hadn't filed yesterday afternoon, but Republican challenger Charles Jeter of Spartanburg did. Jeter served in the Reagan administration's Environmental Protection Agency.

Republican Nancy Harrellson of Marion has filed to challenge Democrat House Majority Whip Jim Clyburn of Columbia in the 6th District.
