Five Republican candidates seeking to fill the late Sen. Lindsey Graham's seat in South Carolina clashed on several national issues during a debate Monday, exposing fissures within the party on topics including the war in Iran, government spending, the filibuster and data center expansion.
The candidates, including current Sen. Darline Graham Nordone, R-S.C., Rep. Ralph Norman, R-S.C., Rep. Russel Fry, R-S.C., businessman Mark Lynch, and former South Carolina Gov. Mark Sanford, largely agreed on broad party consensus points but diverged on specifics.
Filibuster Debate
Senator Darline Graham Nordone, who holds the seat formerly occupied by her brother, announced her support for ending the Senate filibuster, a procedural hurdle requiring 60 votes to pass most legislation. "I am all for -- this is where I differ from my brother -- getting rid of the filibuster to get this done, because eventually the Democrats are going to get rid of it anyway," Nordone stated, highlighting a significant departure from her late brother's stance. Supporters of the filibuster contend it prevents one party from enacting legislation without bipartisan support, while opponents argue it obstructs Republican priorities, such as national voter identification laws.
War in Iran and Congressional Authority
Mark Sanford raised concerns about the executive branch's authority in foreign conflicts, asserting that "Only Congress has the authority to declare war. This decision needs to be made by Congress." The ongoing conflict with Iran, which began nearly six months ago following a U.S.-led bombing in coordination with Israel that killed Ayatollah Ali Khamenei, has extended beyond initial expectations. Lawmakers have debated whether the president has overstepped constitutional war-making powers granted to Congress. While some candidates, like Rep. Russel Fry, expressed support for addressing Iran's nuclear capabilities, Fry emphasized, "No boots on the ground. I’m not a believer in that." He added, "We can finish the mission by defanging Iran and making sure they have no capabilities left."
Data Center Expansion and Local Concerns
Businessman Mark Lynch brought the issue of data center expansion to the forefront, advocating for prioritizing local community concerns over national interests. "It is a pain point for South Carolinians," Lynch said, citing issues such as land use, noise pollution, water consumption, and increased utility costs as detrimental to residents.
Personal and Political Exchanges
The debate also saw personal jabs, with Nordone criticizing Lynch for multiple remarks about her late brother's record on amnesty and marijuana legalization. Lynch had previously run against Lindsey Graham in the 2026 primary, losing by a significant margin.
The Republican primary is scheduled for August 11, with the winner advancing to face Democratic nominee Annie Andrews in the general election on November 3. The race is projected to favor the Republican candidate.
