Columbia, S.C. — Graham, Andrews Clash Over Iran and AI in Debate

Republican Sen. Darline Graham and Democratic challenger Annie Andrews met Sunday night in Columbia for their first and likely only debate before South Carolina voters pick a successor to the late Sen. Lindsey Graham, according to NBC News. The two clashed over President Donald Trump's "one big, beautiful bill," the Iran war, AI data centers, and the price of gas and groceries.

The debate landed exactly three months after Lindsey Graham died unexpectedly at age 71, a timeline Darline Graham noted at the top of the broadcast, NBC News reported Oct. 11, 2026. Darline Graham was appointed to fill her brother's seat after his death in July and is now running to hold it for a full six-year term.

What happened at the Columbia debate?

South Carolina ETV hosted the debate, and the tone turned combative within minutes, per NBC News. Andrews, a pediatrician, cast Graham as untested and unwilling to break with the White House, calling her "the White House's ambassador to South Carolina." Graham countered by labeling Andrews the "most radical liberal" to run for office in the state and tied her to the Democratic Socialist Party.

"Annie Andrews will not stand up to the Socialist Democratic Party; she's only going to join them," Graham said, according to NBC News.

Andrews rejected the framing directly during the exchange, telling viewers Graham had "been told to come out here and call me Bernie, Ocasio, Mamdani — that's what's in her script," per the network's account. Andrews added that she supports the Second Amendment, backs a secure border and favors deporting immigrants who commit crimes, positioning herself as willing to break from national Democrats.

Why is a ruby-red state seen as competitive?

South Carolina remains a state where Trump stays popular with Republican primary voters, NBC News reported. But the outlet described the general-election race as having tightened in its closing weeks, with Democrats believing they have an opening to flip the seat. The clearest data point on how seriously national Republicans are treating that risk: the top Senate Republican super PAC has pledged $5 million to support Graham's campaign, according to NBC News, Oct. 11, 2026.

That spending commitment is the single clearest financial signal in the race so far from the sourced reporting — a seven-figure outside investment in a state Trump carried comfortably in prior cycles.

Where do Graham and Andrews disagree on Iran, AI and Trump's agenda?

The debate's substantive disagreements, as described by NBC News, spanned four areas: Trump's "one big, beautiful bill," the Iran war, AI data centers, and consumer costs for gas and goods. NBC News's account does not detail each candidate's specific position on AI data center policy or the Iran war beyond noting the topics came up, so readers should treat those exchanges as contested ground rather than settled characterizations.

What is attributed directly: Graham's attack linking Andrews to national progressive figures, and Andrews's on-camera denial paired with her stated positions on gun rights, border security and deportation of immigrants who break the law. Andrews framed the core contrast as a willingness to break with her own party, saying she would "always put South Carolina first," per NBC News.

What's at stake historically in this race?

Both candidates are competing for a full six-year Senate term, and NBC News notes the winner will become the first woman elected to the U.S. Senate from South Carolina — a distinction that exists regardless of which candidate prevails, since Graham currently holds the seat by appointment rather than election.

What is the timeline to Election Day?

• July 2026: Sen. Lindsey Graham dies unexpectedly at age 71.
• Following weeks: Darline Graham is appointed to fill her brother's Senate seat.
• Oct. 11, 2026 (Sunday): Graham and Andrews hold their first and reportedly only general-election debate, in Columbia, hosted by South Carolina ETV — exactly three months after Lindsey Graham's death.
• Ahead: General election for the full six-year term, with the Senate Republican super PAC's $5 million pledge already deployed to back Graham, per NBC News.

What do the numbers show?

Two figures frame the stakes, both sourced to NBC News, Oct. 11, 2026. First, $5 million: the sum the top Senate Republican super PAC has pledged to Graham's campaign, a spending level typically reserved for races a party views as genuinely at risk rather than safe. Second, three months: the span between Lindsey Graham's death in July and Sunday's debate, a compressed runway that has left Darline Graham running statewide for the first time while still filling out a term she did not originally seek through election. Neither figure settles who wins; both explain why national Republicans are spending as if the outcome is uncertain in a state Trump has otherwise carried easily.
