Contributing sentiments towards policy:

64% : Frontrunner Donald Trump has cruised to victory in South Carolina's Republican primary with the support of an almost unwavering base of loyal voters.
56% : Trump dominates among conservative voters.
54% : Haley outpaced Trump among college-educated voters, a relative weakness for him that could matter in November as people with college degrees are a growing share of the overall electorate.
46% : A majority believe Trump is a candidate who can emerge victorious in November's general election, while only about half say the same of Haley.
44% : While the outcome puts Trump closer to clinching the Republican nomination, Haley has vowed to press on.
44% : Trump, 77, won in South Carolina with voters who are white and do not have a college degree, one of his core constituencies.
43% : Even though South Carolina Republican voters believe that Trump can win in November, some had worries about his viability.
37% : Voters were also far more likely to view Trump than Haley as someone who would "stand up and fight for people like you" and to say he would keep the country safe.
36% : Trump has an iron grip on the Republican base, but that might not be enough of a coalition to guarantee a win in November's general election.
28% : But about nine in 10 of South Carolina's primary voters were white, making it hard to see if Trump has made inroads with Black voters whom he has attempted to win over.
27% : About half of Republican voters in South Carolina - including about a quarter of his supporters - are concerned that Trump is too extreme to win the general election.
22% : About four in 10 of South Carolina Republicans - including about six in 10 of those supporting Trump - say they have an unfavourable opinion of her.
22% : Haley's voters were much more divided: About half were motivated by supporting her, but nearly as many turned out to oppose Trump.
17% : "Even though she has little prospect to win any of the future races, deep pocket of donors are still prepared to bankroll her because of their antipathy to Donald Trump or to keep her in the running in case Trump's legal troubles mean he has to drop out," Rittansi said.
15% : The other 63 percent identified as moderate or liberal, the two categories that Trump lost to Haley in South Carolina.
