The people who support this nonsense need to be punched.
From Greenpapers SC page:
Each congressional district delegate ... shall be bound during the first ballot at the convention to the presidential candidate who received the greatest number of votes .... If the candidate who received the greatest number of votes in that particular delegate’s home district is not placed in nomination, a delegate must then be bound to the congressional district’s second or third place finisher in the presidential preference primary, respectively. If none of the top three finishers in the congressional district presidential preference primary are placed in nomination, delegates shall be unbound.
Each delegate-at-large shall be bound for the first ballot to the candidate who received the largest number of votes statewide in the presidential preference primary. If the candidate who receives the greatest number of statewide votes in the presidential preference primary is not placed in nomination, a delegate must then be bound to the state’s second or third place finisher in the presidential preference primary, respectively. If none of the top three finishers in the statewide presidential preference primary are placed in nomination, delegates shall be unbound. [South Carolina Republican Party Rules - Rule 11(b)(4), (5)]
He won them fair & square.
Or at least pepper sprayed.
