Donald Trump’s comfortable victory over Nikki Haley was fueled by strong support from White evangelical Christians and voters without college degrees. Big majorities of primary voters favored deporting most undocumented immigrants and said that Joe Biden’s 2020 election was illegitimate, and both of these groups favored Trump over Haley by an overwhelming margin.

See the strengths and weaknesses of Trump and Haley, according to a statewide survey of South Carolina voters as they exited randomly selected precincts across the state Saturday.

Methods: These results are from a survey of 2,126 Republican primary voters as they exited randomly selected voting sites in South Carolina on Feb. 24, 2024. The poll was conducted by Edison Research for the National Election Pool (ABC, CBS, CNN, NBC), The Washington Post and other media organizations. Results were weighted to match vote tallies by region and to correct for differential participation by subgroup. Totals may not add to 100 percent because of rounding.
