South Carolina: Republicans Debate Their Way to a Graham Successor

The Republican primary to fill the late Lindsey Graham's seat in the South Carolina Senate race has moved into its most public phase yet, with back-to-back Nexstar-hosted forums putting Representative Russell Fry, Representative Ralph Norman, former Representative Mark Sanford, and a businessman candidate on stage together. The format has forced the four into direct contrasts on records and positioning rather than dueling press releases, and with no incumbent in the race, the debates carry more weight than they might in a typical cycle — undecided Republican voters have fewer cues to fall back on.

A Public Policy Polling survey, commissioned by a Democratic firm, put Democrat Annie Andrews ahead of Fry 42 to 39 percent in a hypothetical general-election matchup. That result is getting attention, but it should be read with caution: PPP's client relationship gives it an incentive to produce findings that keep Democratic donors engaged, and single-poll snapshots from primary season are notoriously unstable once a nominee is settled and a general-election campaign actually begins. More importantly, the number cuts against every neutral handicapper's read of the race. Cook Political Report and Inside Elections both rate the seat Solid R, while Sabato's Crystal Ball calls it Safe R. When a partisan poll's topline diverges this sharply from three independent ratings, the ratings — grounded in the state's underlying partisan lean rather than a single sample — deserve more weight.

Money is the one place where Andrews has a genuine, verifiable edge. Her campaign reported $10.8 million in total receipts, compared with $6.77 million for Graham and $5.92 million for Mark Lynch on the Republican side. That fundraising gap is real and will fund a serious general-election infrastructure if Andrews wins her primary. But cash totals and poll toplines are different kinds of evidence, and neither has been enough historically to overcome the structural disadvantage Democrats face in South Carolina statewide races. The rating agencies' calculus isn't disputing that Andrews can raise money or that a Democratic pollster can produce a competitive-looking number — it's a bet that the state's fundamentals will reassert themselves once a Republican nominee is settled and the race consolidates.

Inside the Republican field, attention has also turned to special-election candidate Darline Graham, whose viability is being questioned by local Republicans who draw comparisons to Pamela Evette's unsuccessful 2022 run for governor. The comparison is being used as shorthand for skepticism about whether Graham can translate name recognition or local support into a durable statewide primary campaign, though the comparison itself says more about how local operatives are framing the race than about any independent assessment of her chances.

The Senate contest isn't the only South Carolina seat in flux. In the 1st District, Nancy Mace's retirement has been announced, and the seat is currently rated Likely R. That rating reflects the district's partisan composition rather than any specific candidate matchup, and it will be worth watching whether a crowded successor field — as in the Senate race — produces similar swings between partisan polling and neutral ratings once candidates emerge in earnest.

For now, the through-line in South Carolina is a familiar one: a well-funded Democratic challenger and a favorable-looking partisan poll are generating headlines, while the state's structural lean and the independent handicappers' ratings continue to point toward Republican control. Whether that gap narrows will depend less on who wins the next debate than on who emerges from the Republican primary intact.
