Representatives Russell Fry and Ralph Norman filed for South Carolina's special Senate primary on 20 July, neither giving up his House seat to do it. The seat opened when Lindsey Graham died on 11 July. They join interim Senator Darline Graham Nordone, Graham's sister, appointed on 13 July and carrying Donald Trump's endorsement, alongside Duke Buckner, Mark Lynch, Mark McBride, Clark Neilson and Samuel Shepherd1. Filing closes at noon on 28 July, so the field is not yet settled.
South Carolina has no resign-to-run law, the rule that in some states obliges an officeholder to quit one post before standing for another. Fry has said he will keep his House seat and stand for re-election there in November if the Senate primary goes against him2. Neither man faces a choice about anything until January.
Norman has turned that arrangement into an argument against his own side. Whichever of the two wins is sworn into the Senate, his House seat empties on that day, and it stays empty until a separate special election fills it, plausibly well into 20273. Speaker Mike Johnson has no spare votes to lend to a colleague's ambition.
Where resign-to-run statutes do bind, as in Florida and Georgia, they price ambition and thin primary fields, because entering costs the officeholder the job he already has. Without one, the rational move for any House member sitting on a safe seat is to enter every open Senate primary going: lose and you go back to work, win and you move up. The cost does not disappear. It transfers to the conference, which carries the vacancy. Norman can argue against the arrangement and use it in the same week without contradicting himself.
