Donald Trump maintains a double-digit lead in South Carolina ahead of Saturday’s primary, according to a Fox News poll out Thursday.

The billionaire businessman, who won the New Hampshire primary after finishing second in Iowa, leads the field with 32 percent support among likely primary voters. Sens. Ted Cruz and Marco Rubio follow at 19 percent and 15 percent, respectively.


Former Florida Gov. Jeb Bush, whose brother, former President George W. Bush, joined him on the trail in South Carolina this week, sits at 9 percent alongside retired neurosurgeon Ben Carson. John Kasich, who will reportedly be in Massachusetts instead of South Carolina on Saturday, is last at 6 percent.

Trump also leads among evangelical Christians, a key voting bloc in South Carolina. Nearly 60 percent of South Carolina Republicans identify as evangelicals — 31 percent of whom back Trump, compared with 23 percent for Cruz, 17 percent for Rubio and just 10 percent for Bush.

Veterans also favor Trump as commander-in-chief — 37 percent say they will back him. About 22 percent of GOP veterans will vote for Cruz and 15 percent for Rubio.

Cruz, however, holds a slight advantage over “very” conservatives with 31 percent support to Trump’s 29 percent. Rubio is at 14 percent among that group.

And despite Trump’s large share of support, 39 percent of those surveyed said they would “never” vote for him, and 47 percent say he has unfairly attacked Republicans.

Though the primary is just days away, voters’ decisions aren’t set in stone — which could benefit Rubio the most. The Florida senator on Wednesday received a big boost when popular South Carolina Gov. Nikki Haley endorsed his White House bid.

A quarter of likely Republican voters say they could change their minds before they cast votes.

The survey of 759 likely Republican primary voters was conducted via landline and cellphone Monday through Wednesday evening. The margin of error is plus or minus 3.5 percentage points.
