Sen. Lindsey Graham (R-SC) now has four contenders running against him in the Republican primary for his Senate seat.
Orangeburg attorney Bill Connor became the latest challenger to jump into the race, according to The State newspaper.
In 2010 Connor lost the South Carolina lieutenant governor race in a runoff against Ken Ard (who would eventually become lieutenant governor).
Besides Connor, public relations executive Nancy Mace, state Sen. Lee Bright and businessman Richard Cash are running in the primary.
