Darline Graham Is Now a Senator. Here Are the Next Election Dates.

Darline Graham has been sworn in as a U.S. senator from South Carolina, temporarily filling the seat left vacant by the death of her brother, Sen. Lindsey Graham, while the state moves into a fast special-election calendar.

The practical takeaway is that the appointment settles who represents South Carolina in the Senate for now, but it does not settle who will hold the seat when the next Congress begins. South Carolina officials say Graham will serve until January 3, 2027, after voters choose a successor in the November 3, 2026 general election.

What changed

Gov. Henry McMaster appointed Darline Graham on July 13 under South Carolina's vacancy law. His office said she is the first woman to represent South Carolina in the U.S. Senate and will serve for the remaining months of the current term.

The Senate swore her in on July 14. ABC News reported that Senate President pro tempore Chuck Grassley presided, with Sen. Tim Scott of South Carolina and Sen. Katie Britt of Alabama escorting Graham during the ceremony.

Graham has worked in South Carolina public service, including as commissioner of the South Carolina Commission for the Blind since 2019, according to the governor's office. She is not being installed for a full six-year term; she is filling the current vacancy while the election process continues.

The dates to watch

Because Lindsey Graham was the Republican nominee for the 2026 Senate race, state law allows the South Carolina Republican Party to hold a special primary to choose a replacement nominee for the ballot.

Filing for that special primary is scheduled to run from July 21 through July 28. The primary is set for August 11. If no candidate wins outright and a runoff is needed, that runoff is scheduled for August 25.

The general election remains scheduled for November 3. The winner of that race is expected to take the seat when the new Congress convenes on January 3, 2027.

Why it matters

The compressed calendar gives potential Republican candidates only days to decide whether to file and just weeks to campaign before the primary. It also gives voters a short window to separate the temporary appointment from the longer-term choice on the November ballot.

For now, South Carolina has Senate representation again after Graham's death. The larger political question is who emerges from the special primary and whether the compressed race changes what had been a standard reelection contest into a more volatile open-seat campaign.
