South Carolina’s Republican primary is set for Saturday, with Donald Trump expected to win over Nikki Haley despite her substantial spending. Even if she loses, Haley plans to continue her presidential campaign. The state has 50 delegates, awarded on a winner-take-all basis statewide and by congressional district. Trump leads in delegates so far. The state’s political landscape includes four regions, with Trump having broad support. Haley faces an uphill battle due to South Carolina’s conservative and religious GOP primary voters, contrasting with her appeal to Republican-leaning independents.
