As a matter of statistical fact, more than any other demographic, evangelical Christian voters are deciding the 2024 Republican presidential primary.  

According to ABC News exit polls, self-identified born-again Christians comprised 61% of the electorate in Saturday’s GOP presidential primary in South Carolina. They gave 72% of their vote to former President Donald Trump and 27% to former South Carolina Gov. Nikki Haley. (The rest of the primary electorate picked Haley over Trump, 54% to 45%.) In other words, Trump’s landslide victory was sealed by evangelicals.
