South Carolina voters are casting ballots Tuesday in a special Republican primary to determine who will carry the party's banner in November for the Senate seat left vacant by the death of longtime incumbent Lindsey Graham in July. The contest features a wide-open field, with the late senator's sister, Darline Graham, squaring off against two sitting congressmen and other challengers in a race that could head to a runoff.
Darline Graham, who was appointed to fill the remainder of her brother's term, has secured the endorsement of former President Trump and the backing of the National Republican Senatorial Committee. That institutional support gives her a significant advantage in name recognition and fundraising, but her opponents argue that her lack of legislative experience is a liability in a state that has not elected a Democrat to the Senate in decades.
Rep. Russell Fry, a two-term congressman from the Myrtle Beach area, and Rep. Ralph Norman, a conservative stalwart from the Rock Hill region, are both seeking to block Graham's path. Fry has emphasized his work on veterans' issues and his alignment with Trump's America First agenda, while Norman has touted his fiscal conservatism and his record of opposing government spending. Both men have sought to contrast their legislative records with Graham's relative newcomer status.
Also in the race are former Governor and Congressman Mark Sanford, who has been a vocal critic of Trump and has positioned himself as a maverick, and businessman Mark Lynch, who is running on a platform of economic populism. Sanford, who previously held the same House seat now occupied by Fry, has sought to appeal to moderate Republicans and independents, though the primary electorate is heavily conservative.
The primary rules require a candidate to secure at least 50 percent of the vote to win outright. If no one reaches that threshold, the top two finishers will advance to a runoff scheduled for August 25. Political analysts suggest that a runoff is likely given the number of candidates splitting the vote, with Graham and either Fry or Norman considered the most probable pair to advance.
Polls close at 7 p.m. EDT, and results are expected to begin coming in shortly thereafter. The winner of the primary will be heavily favored in November, as South Carolina is a reliably Republican state. The race has drawn national attention as a test of Trump's continued influence in GOP primaries, especially after his endorsement of Graham, who has sought to distance herself from her brother's more moderate legacy while embracing the former president's agenda.
The contest is unfolding against the backdrop of broader midterm dynamics, with primaries in several states setting the stage for the 2026 midterms. In South Carolina, the outcome could signal whether establishment-backed candidates can withstand challenges from more conservative insurgents.
Meanwhile, the late senator's legacy remains a focal point. Just last month, the Pentagon renamed a Charleston base after Lindsey Graham, a move that underscored his long tenure and influence on military and defense issues. Darline Graham has invoked her brother's memory on the campaign trail, but she has also sought to carve out her own identity, emphasizing border security and support for Israel.
As voters head to the polls, the question of experience versus name recognition is central. Darline Graham's bid tests whether name recognition can overcome the experience gap that her opponents have highlighted. The answer may come down to whether the party's base is willing to trust a political newcomer with a full six-year term.
