(Christopher Aluka Berry/Reuters)Lindsey Graham's sister, Darline Graham Nordone, has been named as her late brother's temporary replacement in the U.S. Senate. South Carolina Gov. Henry McMaster announced at a news conference at the state house on Monday that Nordone would serve the remaining months on Graham's current term, which expires in January. A person familiar with the appointment process but not authorized to speak about it publicly said Nardone would be sworn in Wednesday. She will be the first woman to represent the state in the U.S. Senate."It is such an honour," Nordone said. "Lindsey has always been there for me. And now, I will be there for him."Graham died over the weekend at age 71. He never married or had a family of his own, but Nordone was often by her brother's side for the political touch points of his career, speaking at events and appearing in some of his campaign ads. After their parents died at a young age, Graham was left to raise his sister, for whom he later became legal guardian. They were very close, and she was there as he filed re-election paperwork earlier this year, along with her children and grandchildren.WATCH | U.S. Senator Lindsey Graham dead at 71:Republican Sen. Lindsey Graham dead at 71July 12|Duration 2:17Longtime U.S. Republican Senator Lindsey Graham has died unexpectedly at age 71 from a suspected ruptured aorta. Graham was once a vocal critic of President Donald Trump, but eventually became an ardent supporter.Special election next monthA special election will be held next month to pick a new Republican nominee in the general election for Graham's seat. He had been seeking a fifth term this year.The rare open Senate seat has ignited a scramble among South Carolina's most ambitious conservatives, who have been eager to climb the political ladder.Republicans just finished a sprawling and bruising contest to figure out their nominee for succeeding McMaster, who is wrapping up his second term. State Attorney General Alan Wilson won the nomination, overcoming a field that included Lt. Gov. Pamela Evette, Rep. Nancy Mace and Ralph Norman — all of whom are now eyeing Graham's seat following his death over the weekend. How will a special primary work?According to South Carolina law, a one-week filing period for a special primary election begins on the second Tuesday after the candidate's death, or July 21.The special primary election would be held on the second Tuesday after that filing period closes, or Aug. 11. Any necessary run-off would follow two weeks after that, or Aug. 25.From that point, the new nominee would have just over two months to campaign for the general election on Nov. 3.All of this is problematic according to federal law, which requires military and overseas ballots to go out 45 days before any federal election. For the special election primary, that would have been June 27. U.S. Federal Election Commission officials didn't immediately return a message seeking clarity about the process.Who could replace Graham?Graham died on Saturday night, and a preliminary medical examiner report said he suffered a tear in his aorta, known as an aortic dissection. In the hours after Graham's death was announced, South Carolina's Republican circles were already swirling with rumors about possible replacements. U.S. Republican Sen. Lindsey Graham likely died after aorta rupture: medical examinerEvette, who has served nearly eight years alongside McMaster and received his endorsement in the governor's race, is one possibility. She lost the June 23 runoff to Wilson. A person with knowledge of Evette's thinking but not authorized to discuss it publicly said that she was getting encouragement from across the state and feels she would have good chances in the special primary.It's unlikely that any House member would be appointed to finish Graham's current term, since Republicans have such a slim majority in the chamber. However, that doesn't mean that House members won't run for the next full term. A person with knowledge of Mace's thinking but not authorized to speak about it publicly said she was considering the race. Mace is not running for reelection to the House. But another Republican from the state, Rep. Russell Fry, could be a possibility. The two-term lawmaker represents the growing area around Myrtle Beach, and he's been a top Trump ally. Businessman Mark Lynch, whom Graham defeated in the primary, could also jump into the race. A person familiar with but not authorized to speak publicly about the thinking of Mark Sanford — South Carolina's former governor who also served two separate stints in the U.S. House — said he was considering it, too.How does Graham's death affect the general election?No Democrat has won a Senate seat in South Carolina in decades, and Republicans in recent history typically take statewide seats by double digits. When he last ran in 2020, Graham defeated his Democratic opponent, Jaime Harrison, by a 10 percentage point margin. So while history suggests that Graham was en route to a fifth term, Republicans are carefully surveying the landscape.Trump removes remaining heads of Election Assistance CommissionAnalysisWhat the Graham Platner scandal says about Democratic Party's troublesCharleston pediatrician Annie Andrews won the Democratic nomination last month and has raised more than $8 million US in the race, and she had just under $3 million US cash on hand at the end of May, according to federal filings. Graham had taken in $6 million US, with just over $4 million US on hand.In a statement Sunday, Andrews called on South Carolinians to join her "in setting partisanship aside and offering gratitude" to Graham for his service.Harrison, noting that he and Graham "had our share of political disagreements," wrote on social media that he "always appreciated that even in our fiercest political battles, we could still share a conversation, a laugh, and a mutual respect for South Carolina and the institutions we were both privileged to serve."
