Republican Rep. Nancy Mace says she is breaking with former President Donald Trump and is questioning whether Darline Graham, the sister of U.S. Sen. Lindsey Graham, is eligible to appear on South Carolina ballots. Mace’s remarks focus on state ballot-eligibility requirements that have changed under new South Carolina laws related to voting in Republican primaries. She argues that Darline Graham may not meet the applicable rules for the ballot, though the sources provided do not describe the specific eligibility standard or any formal ruling from state election officials. The reporting characterizes Mace’s comments as a departure from Trump-aligned positions, framing the issue as both a test of candidate qualifications and a potential dispute over how the state’s updated primary ballot rules are applied. The accounts agree on the core elements: Mace’s public break with Trump, her challenge to Darline Graham’s “qualified” status, and her reference to the effect of recent South Carolina changes governing Republican primary ballot eligibility. The sources do not indicate that Mace has filed a legal challenge in the provided excerpts, nor do they report the final outcome of any eligibility review.
