Graham Nordone takes the Senate runoff

3 min read

Darline Graham Nordone beat Ralph Norman 193,486 to 175,412 in South Carolina's Republican Senate runoff on Tuesday 25 August. Neither Norman nor Russell Fry won, so no House seat falls vacant and the alarm this briefing raised in July comes off the board.

Key takeaway

Graham Nordone took the nomination on rising turnout, and no South Carolina House seat is vacated.

Darline Graham Nordone beat Ralph Norman 193,486 votes to 175,412 in South Carolina's Republican Senate runoff on Tuesday 25 August, taking 52.45 per cent across all 46 counties. 1 The contest fills the seat left by Lindsey Graham, who died on 11 July ; Graham Nordone, his sister, was appointed to it two days later by Governor Henry McMaster and carries the president's endorsement. She fought both rounds as the sitting senator rather than as a challenger. 2 A nine-candidate scramble reads differently once you notice that one of the nine already had the office, the staff and the letterhead.

Nobody cleared fifty per cent on Tuesday 11 August. Graham Nordone led on 32.75 per cent, Norman took 24.62, Russell Fry 19.66 and Mark Sanford 14.94, from the twelve who filed and the nine the Commission certified , . 3 Turnout then rose by 33,343 between the rounds, from 335,555 to 368,898. South Carolina runoffs normally shed voters rather than gain them, so the second round drawing a bigger electorate than the first is the unusual number in the certified result.

Fry and Norman had entered without giving up their House seats , and this briefing warned that a win by either would strand a South Carolina House seat until well into 2027. Neither won. No seat is vacated, the delegation goes into November intact, and the warning comes off the board. 4

The National Republican Senatorial Committee (NRSC) put $165,205 behind Graham Nordone on Wednesday 29 July, two buys of $76,135 and $89,070 through the payee Medium Buying, filed with the Federal Election Commission (FEC) under transaction type 24C, the code for a party committee spending in concert with its own candidate. 5 That channel only opened on 30 June, when the Supreme Court struck the coordinated-spending caps . Set it against the outside money: all spenders together reported $21,459,150 of independent expenditure in this race across 176 filings . 6 The party's newly legal buy amounts to 0.77 per cent of what was already being spent around it, which means the new channel changed the paperwork here rather than the airwaves.

Deep Analysis

In plain English

South Carolina held a special election to permanently fill the Senate seat left vacant by Lindsey Graham's death. Because so many Republicans ran, nobody won a majority in the first vote on 11 August, so the top two, Darline Graham Nordone and Ralph Norman, went to a head-to-head runoff on 25 August. Graham Nordone, who had been serving as the appointed placeholder senator and is Lindsey Graham's sister, won that runoff and will now serve under her own mandate rather than by appointment. Norman and the other House member in the race, Russell Fry, both keep their existing House seats since neither won.

Deep Analysis
Root Causes

The runoff happened because South Carolina requires an outright majority in a special primary with more than two candidates, and a crowded nine-candidate field split the vote: Fry and Norman between them denied Graham Nordone the votes she needed despite her incumbency and endorsement.

The turnout increase in the runoff is structurally unusual because South Carolina runoffs typically see turnout fall as the field narrows and casual voters drop off; a rise of 33,343 votes points to a mobilisation effort in the two-week runoff window rather than ordinary attrition.

What could happen next?
  • Consequence

    South Carolina's Senate seat now has an elected, not merely appointed, occupant heading into the 3 November general election.

  • Meaning

    A runoff turnout increase against the historical pattern suggests South Carolina Republican voters treated the second round as the real contest, a dynamic other campaigns may study for late mobilisation in low-turnout special elections.

Cook Political Report
Cook Political Report
Cook Political Report published a dated House ratings snapshot on 11 September and changed no seat's rating, holding at 206 Democratic to 208 Republican with 21 tossups since its 3 September batch. Publishing without a change is a dated decision, not an oversight, leaving Republicans ahead on seats while Democrats lead the national vote by 6.6 points.

A Justice Department official told the Las Vegas Review-Journal that preservation letters like the one sent to Aguilar go to states the department is in active litigation against over incomplete voter registration lists. The department would not answer the paper's specific questions about the personal investigation notice riding inside the same letter.
Francisco Aguilar
Francisco Aguilar
Nevada Secretary of State Francisco Aguilar publicly rejected Justice Department pressure on 12 September, days after a 4 September letter combined a records-preservation demand with a personal notice that he is under investigation. He said he will not fold until a judge orders him to, making his office's compliance a political stand rather than a routine filing.

Justice Brett Kavanaugh denied Missouri's state-track stay application alone on 8 September without referring it, then sent the separate federal-track application in Onder v. State of Missouri to the full Court, which stayed it on 10 September. His choice of which application to keep and which to share decided how much of the fight one justice controlled.

Robert Onder and three other Republican plaintiffs won a temporary restraining order from Chief Judge Stephen R. Clark on 8 September ordering Missouri to use HB 1, then lost it when the Supreme Court stayed it on 10 September. Their federal route ran parallel to Hoskins's own reversal and ended the same way, with the 2022 map governing 3 November.

Richard Von Glahn and People Not Politicians won Von Glahn v. Hoskins on 3 September, persuading the Missouri Supreme Court that their referendum petition stripped HB 1 of effect and sent it to voters as Proposition A. The contempt finding against Hoskins this week confirms their win held even after the state's chief election officer tried to reverse it.
