WASHINGTON, DC: Rep Nancy Mace has publicly broken with President Donald Trump over South Carolina's closely watched Senate race, questioning whether his endorsed candidate, Darline Graham, is even eligible to appear on the Republican primary ballot.

The unusually direct challenge comes as local GOP officials pursue a formal review of Graham's qualifications under the state's newly revised election rules.

While Trump has urged Graham, who was appointed to temporarily fill the Senate seat following the death of her brother, Sen Lindsey Graham, to seek a full term, Mace has instead endorsed Rep Ralph Norman, setting up a rare confrontation between one of Trump's most influential endorsements and a prominent Republican ally.

Speaking about Graham's candidacy, Mace said she was unconvinced the newly appointed senator even qualifies to compete in the Republican primary.

"She has no record and I'm not even sure that she's qualified to be on the ballot," Mace said, pointing to questions over whether Graham participated in enough recent Republican primary elections to satisfy South Carolina's updated ballot-access requirements.

Rather than backing Trump's choice, Mace endorsed Norman, calling him a "tried-and-true conservative" with a consistent voting record and arguing Republicans have a rare opportunity to send a reliable conservative to the Senate.

Eligibility review adds uncertainty

The dispute extends beyond Mace.

South Carolina GOP Chairman CJ Westfall confirmed he is seeking a formal determination on whether Graham satisfies the party's eligibility standards.

According to Mace, a state election law enacted this July requires Republican candidates to have voted in at least two of the last three Republican primaries, though it remains unclear whether Graham meets that threshold.

The review has transformed what began as an endorsement battle into a broader legal and political dispute over who can appear on the ballot.

Race tests Trump's political influence

Trump announced his endorsement after meeting Graham at the White House, urging her on Truth Social to "run, Darline, run."



But Mace dismissed suggestions that Trump's backing alone would determine the outcome, arguing South Carolina Republicans are independent-minded voters who make their own decisions at the ballot box.

The clash marks one of the most significant Republican divisions in the early stages of the Senate race, placing Trump's political influence, ballot eligibility rules and the future direction of South Carolina's GOP all under the spotlight.
