A fourth Republican threw his hat into the candidate ring just before the Saturday filing deadline in the race to fill John Courson's vacated S.C. Senate seat.
John Holler joins Republicans Benjamin Dunn, Christian Stegmaier and Bill Turbeville and Democrats Dick Harpootlian, Kyle Lacio and Dayna Alaine Smith in competition for the District 20 Senate seat.
Party primaries for the Senate special election will happen Aug. 14, and voters will choose a new senator during this fall's regular election on Nov. 6.
The winner will serve the last two years of Courson's term.
Courson resigned June 4 after pleading guilty to misconduct in office in the State House corruption probe, triggering the special election.
Filing for the seat ended Saturday at noon.
District 20 stretches from the southern neighborhoods of Columbia to the northwest, along Interstate 26 into portions of Lexington County.
