Since Roe vs. Wade was overturned, a number of Republican-led states have passed laws that prohibit abortion after 6 weeks of pregnancy or when a fetal heartbeat can be detected (though many of these laws have been blocked in court). According to June polling from Harris Poll for the Harvard University Center for American Political Studies, Republicans favor similar laws in their states by a margin of 30 percentage points (65 percent support and 35 percent oppose).

DeSantis brushed off concerns that his signing a six-week abortion ban in Florida will hurt him on the national stage.

"I would say we sold the biggest election landslide victory in the history of the Republican party and the state of Florida in 2022," DeSantis countered. "That's what I did. We can win."

DeSantis argued "we're better than what the Democrats are selling" but ultimately demurred on whether he'd support a six-week ban at the national level.

"I will stand on the side of life," he responded.

DeSantis wouldn’t directly answer when the moderators asked him if he would sign a national abortion ban, and Pence pounced. He comes from the social conservative wing of the party, and supports a national ban. This isn’t the first time Pence has criticized DeSantis for not being conservative enough on abortion, either.

Haley reiterated her calls for "compassion" when the country debates abortion, though she declined to state whether she would support a federal ban on the procedure.

Haley noted the uphill climb to a federal ban, referencing the 60-vote filibuster in the Senate, but said she would oppose late-term abortions and punishments for women who receive abortions.

"Can't we all agree that we should ban late term abortions? Can't we all agree that we should encourage adoptions? Can't we all agree that doctors and nurses who don't believe in abortion shouldn't have to perform them? Can't we all agree that contraception should be available? And can't we all agree that we are not going to put a woman in jail or give her the death penalty if she gets an abortion? Let's treat this like the like the respectful issue that it is," she said.

Trump maintains a lead of 28 percentage points over his nearest competitor in South Carolina, according to the latest polls.

Haley and Scott, the two candidates from South Carolina, are both polling higher in South Carolina than they are nationally, according to our polling average. Trump is polling about 7 points lower in South Carolina than in national polls.

Only one pollster, the Manhattan Institute has tested the favorability of Republican candidates in South Carolina since July 1. That survey found Scott and DeSantis had the highest net favorability in the state (+56 and +55 percentage points, respectively), and Trump and Haley close behind (+39 and +33 points, respectively). Pence had a net favorability of +1 point, and Christie was underwater by -36 points.

Economic issues are most important to Republican primary voters in South Carolina, according to a July survey from Fox Business/Beacon Research/Shaw & Co. Research. Fifty-one percent of Republican voters said economic issues would be most important for deciding their vote. Twelve percent each said immigration issues, social issues and foreign policy were most important.

In an August survey by National Public Affairs, 40 percent of South Carolina Republican voters said that Trump wouldn’t lose their support even if he did not show up to the debate. Twelve percent said that they support Trump, but if he didn’t debate they would be open to or definitely supporting someone else, 32 percent said they wouldn’t vote for Trump regardless, 9 percent said they probably wouldn’t watch the debate anyway and 6 percent were unsure.
