Who could replace Lindsey Graham? South Carolina's next steps after senator's death

CHARLESTON, S.C. (AP) — The death of Sen. Lindsey Graham, who was running for a fifth term when he passed away over the weekend, began a tumultuous new chapter in South Carolina politics during a year that has already been full of upheaval.

As the conservative state's senior senator and an influential ally of President Donald Trump, Graham was presumed to be on a glide path toward reelection.

Now, Gov. Henry McMaster must choose a temporary replacement who can serve until January while the state also prepares a special primary so voters can choose a new Republican nominee for the general election.

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.

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 runoff 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 general election primary, that would have been June 27. Federal Election Commission officials didn’t immediately return a message seeking clarity about the process.

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. Given the proximity of November's election, it's likely that whomever McMaster appoints could be a top contender in the special primary, although it's possible that McMaster's choice will only serve as a temporary caretaker.

Evette, 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.

U.S. Rep. Joe Wilson, a rumored replacement, said he assured Trump on Sunday that “my goal is to remain in the House to keep his two-vote majority for the American people!!!”

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.

A spokesman for businessman Mark Lynch, whom Graham defeated in the primary, didn't return a message Sunday.

Treasury Secretary Scott Bessent, who lived in South Carolina prior to joining the Trump administration, has fielded calls about potentially replacing Graham but doesn’t have interest in the role and enjoys working for the president, according to a person who requested anonymity to describe private conversations.

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.

Charleston pediatrician Annie Andrews won the Democratic nomination last month and has raised more than $8 million in the race, and had just under $3 million cash on hand at the end of May, according to federal filings. Graham had taken in $6 million, with just over $4 million 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.

Noting that he and Graham “had our share of political disagreements,” Harrison 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.”

Graham leaves a major void in the Senate, where seniority can determine influence. He served more than two decades in the chamber, positioning himself to lead committees and set the agenda.

Sen. Tim Scott, South Carolina's junior senator, has only been in office since 2012 — short by the state's standards. Fritz Hollings served for 38 years and Strom Thurmond was there for 47.

Scott, who co-chaired Graham's reelection effort, described his former colleague as “irreplaceable.”

“America lost a statesman, but I lost a friend,” he told ABC's “This Week."

DUBAI, United Arab Emirates (AP) — The United States and Iran each asserted Monday they controlled the Strait of Hormuz after a weekend of attacks stretching across the wider Middle East, further threatening any diplomacy to end the war.

The attacks, sparked by Iran striking a container ship Sunday in the strait off the coast of Oman, again underlined that the waterway that once saw a fifth of the world's traded crude oil and natural gas pass through it remained the key issue in negotiations. The narrow mouth of the Persian Gulf has seen shipping disrupted since the start of the war as Iran maintained a chokehold on it by attacking commercial vessels around it, intimidating shippers.

Iran and the U.S. are nearly at the midway point of the 60-day period of an interim deal that was supposed to set up talks for a permanent end to the war. Instead, it has devolved into a series of attacks over the strait and its future, worrying world leaders the Iran war fully could resume.

“A return to full-scale hostilities would have catastrophic consequences,” United Nations Secretary-General António Guterres said in a statement.

The U.S. military’s Central Command described its forces as hitting dozens of sites in the strikes Monday, including air defense systems, radar sites, missile and drone equipment and small boats.

“The Strait of Hormuz is a vital maritime corridor for global trade,” Central Command said. “Iran does not control it.”

Iran's paramilitary Revolutionary Guard, a key power center in the country's theocracy that controls its ballistic missile arsenal, sharply rejected America's statement.

“The Strait of Hormuz is our territory, and we will not allow a rogue and child-killing army from the other side of the world to continue its illegal interference in it,” the Guard said.

Missile alert sirens sounded twice Monday in Bahrain, home to the U.S. Navy’s 5th Fleet, and Kuwait said it was intercepting hostile fire. There was no immediate word on damage in either country.

Iranian state media acknowledged the latest attacks on its soil early Monday, describing explosions in several locations with at least one person being killed.

Iranian attacks on Sunday stretched Bahrain, Kuwait, Qatar, Jordan and even Oman — whose territorial waters with Iran make up the strait. Oman, which long has been an interlocutor between Tehran and the West, summoned an Iranian diplomat to criticize the attack.

Meanwhile Monday, a base belonging to the armed wing of the Kurdistan Freedom Party, an Iranian Kurdish opposition group based in Iraq’s semiautonomous northern Kurdistan region, came under drone attack. Rebaz Sharifi, commander of the Kurdistan Militia Corps, said the strikes targeted the group’s Chamshar base, without giving details on casualties or damage. No group immediately claimed responsibility.

The U.S. military early Sunday said it hit some 140 targets, including missile and drone launch sites, ammunition dumps, communication equipment and other sites — a far-heavier set of attacks than in two previous rounds of strikes in the last week.

“We bombed the hell out of them last night,” U.S. President Donald Trump told NBC’s “Meet the Press.”

Iran retaliated by attacking nations in the region hosting U.S. military forces, while insisting it alone must control the strait and potentially charge vessels for traveling through it.

“The era of one-sided deals is OVER,” Mohammad Bagher Qalibaf, the speaker of Iran’s Parliament and a main negotiator, wrote. “We told you: keep your word or pay the price. Reality is knocking.”

Iran described the strait as being closed, while the U.S. military and Trump asserted that the strait remained open.

Iran’s chokehold on the strait, however, has loosened as the U.S. military provided support to vessels moving along a southern route hugging the coastline of Oman. That new route has angered Iran, which launched repeated attacks on ships using it.

Iran’s grip on the strait led to a global energy crisis, though oil prices have sharply dropped since wartime highs of $120 a barrel.

Trump suggested last week that the interim deal in the war was “over.” But mediators, including Pakistan, Qatar and Egypt, have continued efforts to reach a final agreement to end the war.

A regional official involved in mediation, speaking on condition of anonymity to discuss talks, said efforts to shore up the ceasefire continued Sunday. Pakistan said its foreign minister spoke by phone with Iran’s top diplomat and urged “de-escalation” on both sides.

Iran’s new supreme leader, Ayatollah Mojtaba Khamenei, unseen since the war began, on Saturday vowed in his first statement since the funeral of his father, Ayatollah Ali Khamenei, that Iranians would avenge his killing.
