South Carolina Democratic primary voters, more than half of whom are expected to be African American, say former Vice President Joe Biden is the best candidate to handle racial issues. Even among black voters, he bests California Sen. Kamala Harris, who pressed Biden on the issue during the first Democratic debate. Biden apologized for remarks he made about working with segregationist senators in the 1970s at a Saturday campaign event in Sumter, S.C.

A Fox News Poll released Thursday finds Biden leading on an array of other key issues as well.

Overall, Biden garners 35 percent among South Carolina Democratic primary voters in the race for the party’s nomination -- over twice the support of any other candidate. Bernie Sanders receives 14 percent and Kamala Harris is close behind at 12 percent.

All others trail, including Elizabeth Warren (5 percent), Cory Booker (3 percent), Pete Buttigieg (2 percent), and John Delaney, Marianne Williamson, and Andrew Yang (1 percent each). One in five is undecided -- a group that includes twice as many women (25 percent) as men (12 percent).

South Carolina’s Democratic primary is Feb. 29, 2020.

Among black voters, Biden’s support hits 41 percent, with Sanders at 15, Harris 12, Booker 4, Warren 2, and Buttigieg, Tim Ryan, and Williamson at 1 percent each.

Among white voters, Biden receives 25 percent support, followed by Harris at 13, Sanders 12, and Warren 11.

Biden holds wide leads among voters over age 65 (+36 points), moderates (+25), and both men (+17) and women (+25).

Asked which candidate can best handle racial issues, the largest number (24 percent), pick Biden. They also prefer him on the economy (36 percent), immigration (33 percent), and health care (32 percent).

Harris comes in second on racial issues (21 percent) and immigration (12 percent) and is fourth on health care (8 percent, just behind Warren’s 9 percent) and the economy (6 percent, behind Warren’s 9 percent).

Sanders is second on the economy (15 percent) and health care (19 percent) and is third on immigration (11 percent, one point behind Harris) and racial issues (15 percent).

While Biden is preferred over Harris by 3 points on which candidate will best handle racial issues, his advantage increases to 10 points among black voters. White voters pick Harris by nine.

When asked specifically whether Biden would be better or worse on racial issues than the other candidates, primary voters express confidence in the former vice president. Thirty-four percent think Biden would be better, including 40 percent of blacks and 23 percent of whites.

Only 8 percent think Biden would be worse on racial issues than the other candidates, while 48 percent say about the same.

On which candidate is “most in touch with the concerns of people like you,” it’s Biden again: 28 percent compared to 17 percent for Sanders and 15 percent for Harris. That also holds true among black voters: Biden (31 percent), Sanders (17 percent) and Harris (16 percent).

"Getting poor reviews for a summer debate performance hasn't undone the fact that Biden has a strong following among both white and black voters in South Carolina. He's the big dog there," says Republican pollster Daron Shaw, who conducts the Fox News Poll with Democrat Chris Anderson.

By a 52-26 percent margin, South Carolina primary voters say supporting the candidate who can oust Donald Trump is more important than backing the candidate they like the most.

Those prioritizing defeating Trump are significantly more likely to support Biden (41 percent) than Harris (14 percent) or Sanders (11 percent). Biden also comes out on top, albeit by a much smaller spread, among those saying it’s more important to support their favorite candidate: Biden (29 percent), Sanders (25 percent), Harris (11 percent) and Warren (8 percent).

More than 8 in 10 would be satisfied with Biden as the nominee, nearly 50 points more than the number who support him, and far more than would be satisfied with the other top candidates.

Overall, 83 percent would be happy with Biden winning the nomination, while 73 percent who would be satisfied if Sanders won, 68 percent Harris, 66 percent Warren, and 59 percent Booker.

Among black voters, 87 percent would be happy with Biden as the nominee, 79 percent with Sanders, 71 percent Harris, 66 percent Warren, and 62 percent Booker.

Eighty-nine percent of those satisfied with Harris as the nominee would be happy if Biden wins, while 73 percent of those satisfied with Biden would be okay with Harris.
