The South Carolina Republican primary is the fourth presidential nominating contest of 2024 but only the second head-to-head matchup between former President Donald Trump and former U.N. Ambassador Nikki Haley.

President Trump holds a commanding advantage in South Carolina polls, leading Ms. Haley with 65 percent to her 32 percent in an average of recent polls reported by FiveThirtyEight. That margin has changed little since the first of the year.
