Nancy Mace said Darline Graham may not qualify for South Carolina’s Republican Senate primary ballot, arguing it is unclear whether she voted in two of the last three GOP primaries as required under a new July state law.
The challenge came just after Graham announced she will enter next month’s special primary to seek a full Senate term after being appointed to fill the vacancy left by her brother, Lindsey Graham.
CJ Westfall, a local South Carolina GOP chairman, said he is seeking a formal determination on Graham’s eligibility, citing voter concerns over her voting history and lack of political experience.
Mace, who ruled out her own Senate run on Monday, instead endorsed Rep. Ralph Norman and openly split with Donald Trump, who urged Graham to run after a White House meeting.
The break tests how much Trump’s endorsement can shape a South Carolina Republican primary that Mace says will be decided by independently minded conservative voters.
