# South Carolina U.S. Senate 2026 > [!warning] Open seat — incumbent died in office (July 11, 2026) > Lindsey Graham **won the June 9 Republican primary** for renomination, then **died on July 11, 2026** of an aortic dissection (see [[Lindsey Graham]]). His death opened both his sitting U.S. Senate seat and his spot on the November ballot, forcing a special primary for a replacement nominee. The pre-death analysis below is preserved as history; the live state of the race is in *Graham's death and the scramble* immediately following. ## Graham's death and the scramble (July 2026) Graham's July 11 death created a **double vacancy**: the current Class II seat (which Governor [[Henry McMaster]] fills by appointment until the November general election under S.C. Code §7-19-20) and the Republican nomination Graham had just secured on June 9. South Carolina law requires a **special primary** to choose a replacement nominee. Reporting in mid-July identified a scrambling field. [[Darline Graham]], the late senator's sister and a political unknown tapped to serve out the remaining months of his term, entered the race to replace him and picked up **Trump's swift endorsement**. Her lack of political experience drew immediate skepticism. Challengers in the special primary included U.S. Reps. **Russell Fry** and [[Ralph Norman]], former Governor **Mark Sanford**, and businessman [[Mark Lynch]] — who had run against Graham in the June 9 primary and relaunched his campaign within days of the death. The seat remains **Solid R** at the general-election level; as before, the Republican contest was the whole primary story. > [!success] Resolved — the successor sequence is settled > This section previously carried a fast-moving warning dated 2026-08-12 and left the successor field as plain text pending page decisions. Both are now closed. The **special primary was held 11 August 2026** (Darline Graham 32.8%, Ralph Norman 24.6%, Russell Fry 19.7%, Mark Sanford 14.9%, Mark Lynch 5.9%) and the **runoff on 25 August 2026** went to Darline Graham, **193,486 to 175,412 — 52.4% to 47.6%**. [[Darline Graham]] and [[Annie Andrews]] now have pages and are wikilinked throughout. Fry and Sanford remain plain text by choice: neither is on the November ballot. ## Pre-death analysis (through June 2026) — preserved as history ## Snapshot > [!important] This race was reset by a death — updated 2026-08-31 > The prior version of this page described [[Lindsey Graham]] running for a fifth term. **Graham died in office on 11 July 2026** (aortic dissection, age 71). Everything about the race changed afterward. **[[Darline Graham]] is the Republican nominee** — Lindsey Graham's sister, appointed to the seat by Governor [[Henry McMaster]] at Trump's suggestion and sworn in mid-July 2026, becoming the first woman to represent South Carolina in the Senate. She then won the **August 2026 special Republican runoff over Representative [[Ralph Norman]]** with Trump's endorsement, and is favored in November; Cook moved the race Solid R → **Likely R** on Sept 23, 2026. **Superseded pre-death dynamics**, retained for the record: Graham had Trump's endorsement and faced the most serious primary challenge of his career on June 9. **Paul Dans** (former OMB Chief of Staff and a principal [[Project 2025]] architect) launched a primary run, withdrew April 10, 2026 and endorsed **Mark Lynch** (businessman, anti-establishment), consolidating the anti-Graham MAGA lane. Mid-March Pulse Opinion polling showed Lynch outperforming Graham on an "informed ballot." The wedge was Graham's hawkish Iran/Israel posture generating MAGA backlash as Trump's own position shifted. None of that determined the outcome; his death did. ## The appointment-to-nomination sequence This is the vault-relevant part. A senator died, the governor appointed **the senator's sister** on the president's suggestion, and the appointee then converted the appointment into a nomination within six weeks — over a sitting congressman, on the strength of the same president's endorsement. Darline Graham had no prior electoral record. During the primary debate she said of national security, "I'm just going to be honest here. I'm not that informed on national security," and that it was "not my thing, not my area of expertise." Trump defended the answer as honest and the endorsement held. She won anyway. That sequence is a clean measurement of what a Trump endorsement is currently worth in a Republican primary: enough to convert an unelected appointee with an acknowledged subject-matter gap into a Senate nominee against an experienced officeholder. ## Incumbent - **[[Lindsey Graham]]** (R) — senator since 2003. Former U.S. Rep (SC-03, 1995–2003). Four terms; re-elected 2020 with 54.5% over Jaime Harrison ($130M+ Harrison spend — most expensive losing Senate race in history). **Trump-endorsed** for 2026. [[Senate Judiciary Committee]] ranking/chair. ## Republican primary (June 9, 2026) - **Lindsey Graham** — incumbent, Trump-endorsed. **84.5% implied probability** in Polymarket primary market as of April 2026. But Pulse Opinion "informed ballot" showed Lynch leading — soft-support warning. - **Mark Lynch** — businessman; anti-establishment, anti-interventionist lane. Pre-Dans withdrawal: **$5.5M raised** (robust for a primary challenger). - **Paul Dans** — former OMB Chief of Staff under Trump I; **primary architect of Project 2025**. Launched campaign, then **withdrew April 10** and endorsed Lynch to consolidate the anti-Graham vote. Primary: June 9. Runoff June 23 if no candidate clears 50%. ## Democratic primary (June 9, 2026) — decided **[[Annie Andrews]] won the nomination outright, no runoff required.** Certified returns: | Candidate | Votes | Share | |---|---|---| | **Annie Andrews** | 226,075 | **61.5%** | | Brandon Brown | 110,962 | 30.2% | | Kyle Freeman | 30,374 | 8.3% | Three candidates appeared on the ballot; the pre-primary field listed here previously also named Catherine Fleming Bruce and Christopher Giracello, neither of whom received certified votes. South Carolina has not elected a Democrat to the Senate since Fritz Hollings in 1998, and the pre-death version of this page called the Democratic nomination a structural impossibility. **That judgment is no longer safe to restate.** Cook moved the race Solid R → Likely R on 23 September 2026, and late-August polling of Graham against Andrews ranged from Graham +13 to Andrews +3 depending on house and sample (see [[Annie Andrews]] for the table, which is deliberately not averaged). ## Ratings history - **2026-09-23 — Cook: Likely R** (from Solid R) — the first time this cycle the seat has been rated anything but safe. One of three Senate shifts toward Democrats that day, with Georgia and Kansas. - 2026-04 — Cook: Solid R - No expected movement - **Primary competitiveness does not affect general-election rating** — a Lynch upset is still Solid R ## Key dates - 2026-03 — SC filing deadline (passed) - 2026-04-10 — Dans withdraws, endorses Lynch - 2026-06-09 — SC primaries - 2026-06-23 — runoff (if no candidate clears 50%) - 2026-11-03 — general election ## Money - Graham: **$19M+** cycle total — well-positioned - Lynch: $5.5M pre-Dans withdrawal; consolidated anti-Graham MAGA fundraising expected post-merger - Trump's specific investment in defending Graham is a post-April question ## Intel notes - **The Dans/Project 2025 dynamic**: Dans is one of the most influential non-elected MAGA strategists of the [[Second Trump Administration]] era. His Senate entry was a watershed signal of MAGA establishment discontent with Graham. His April 10 withdrawal + endorsement is a deliberate consolidation strategy, suggesting Dans prioritized defeating Graham over his own candidacy. - **Iran foreign policy wedge**: Graham's long-time hawkish posture on Iran strikes has become a liability in a MAGA primary environment where Trump's own position has moved toward de-escalation. Foreign Policy Journal (April 18) frames this as the biggest-ever primary threat of Graham's career. - **Trump endorsement but not protection**: Trump endorsed Graham but has not publicly attacked Lynch or Dans — an unusual restraint that suggests Trump's endorsement is transactional (Graham votes reliably in Senate) rather than enthusiastic. Watch for Trump rally-appearance patterns in May/June. - **2020 baseline context**: Graham won 2020 by 10 pts after absorbing Jaime Harrison's $130M Democratic spend. His structural R-state advantage remains real; the primary is the only live question. ## Related KB entities - [[Lindsey Graham]] — incumbent (existing People/ entry) - [[MAGA]] — Lynch/Dans as MAGA primary pressure - TBD: [[Paul Dans]] — Project 2025 architect, primary candidate turned endorser - TBD: [[Mark Lynch]] — anti-establishment R primary challenger - TBD: Project 2025 (Organizations/ entry) ## Content leads - **Blog**: "The Dans-Lynch Merger Against Graham" — MAGA primary strategy as a coordinated operation, with Project 2025 architect as case study - **Data**: Graham's Iran/foreign-policy voting record vs. 2025-2026 MAGA base polling on intervention - **[[YouTube]]**: Paul Dans explainer — from Project 2025 to SC Senate runner - **Breaking**: June 9 primary night coverage ## Outside spending ### Outside-money log — FEC Form 24 notices ### Receipt date 2026-10-09 — $4,289,535.27, and South Carolina becomes a money race South Carolina took **$4,289,535.27** across **14 Schedule E lines** on e-file receipt date **2026-10-09** — **$3,418,784.80 (79.70%) negative** and **$870,750.47 (20.30%) positive**.

A party-aligned super PAC putting $1.55M against the Democratic nominee 25 days out, in a **Likely R** open seat created by [[Lindsey Graham]]'s death in office on 2026-07-11, is the same reallocation behaviour the vault recorded when SLF entered [[KS-Sen-2026]] on 2026-10-02.
