Trump leads Haley by a 35 point margin in the Palmetto State primary, a new survey found. AP

“Of the 69% who approve of her gubernatorial job performance, Trump still wins by a significant margin, 56%- 40%,” the pollster found.

Attack ads against Trump in South Carolina have also done little to win support for Haley. 

Among the 59% of South Carolinians who have seen a negative ad targeting the former president, Trump leads 64% to Haley’s 33%. 

Former Rep. Liz Cheney’s (R-Wyo.) recent plea for Haley to stay in the race until at least Super Tuesday has also backfired on the former South Carolina governor, the poll found. 

Only 17% of those polled have a favorable opinion of Cheney, while 58% have an unfavorable view of the former congresswoman.
