Sources re-checked September 25, 2026 · How we research

  • This election fills the Class II Senate seat formerly held by Lindsey Graham (R), who won renomination in the June 9, 2026 Republican primary and died on July 11, 2026. Gov. Henry McMaster appointed Graham's sister, Darline Graham, to the seat on July 13, 2026. A special Republican primary (August 11) and runoff (August 25) were held to select the party's replacement nominee; Darline Graham won that runoff and appears on the November 3 general-election ballot.[1]
  • Annie Andrews won the Democratic primary on June 9, 2026 with 61.5% of the vote, defeating Brandon Brown and Kyle Freeman.[1]
  • Kasie Whitener won the Libertarian Party's nominating convention on April 11, 2026.[1]

Issue evidence — side by side

Recorded votes, documented positions and candidates’ own words are shown with sources. “In their own words” quotes a candidate on the topic without inferring a stance. Votes describe specific bills or motions; they do not establish overall support or opposition to a broad issue. A dash means our research has no evidence on that topic, not that the candidate has no position.

Research notes & limits

Basic-tier research. Darline Graham was appointed to this seat in July 2026 after Lindsey Graham's death; her federal key-vote and FEC data (if added later by script) will reflect only her short tenure. This slate and the Graham appointment/death were independently confirmed against Wikipedia, CBS News, and the official senate.gov senator roster (which lists 'Graham, Darline' for South Carolina, Class II), since the sole cited source was Ballotpedia. Andrews's summary originally called her a 'Charleston pediatrician' citing only her Ballotpedia page, which does not state her profession; corrected to cite her campaign website, which confirms she is a pediatrician (no independent confirmation that she practices in Charleston specifically, so that detail was dropped). Five independent candidates (Jack Ellison, Cindy Glaser, Paul Sedletsky, Edward Strunge, Reece Wright-McDonald) were removed on 2026-10-19: Ballotpedia's race page (s1) lists them under 'Withdrawn or disqualified candidates', and SC Daily Gazette (s18, Oct. 12, 2026) describes the ballot as Andrews, Graham, Whitener and Hackett only; a Democratic write-in candidate (Catherine Fleming Bruce) is not included per the write-in exclusion in the research standard's ballot scope. Biography pass: Ballotpedia's 2026 race page and candidate pages list Jack Ellison, Cindy Glaser, Don Louis, Paul Sedletsky, Edward Strunge and Reece Wright-McDonald under 'Withdrawn or disqualified candidates', so the independents' ballot status should be rechecked; no biographical information was found for them or for Mark Hackett beyond his earlier campaigns.
