Donald Trump sweeps South Carolina Republican primary
The overwhelming result will support calls from Trump's supporters for Haley, his final opponent, to withdraw from the race.
With five races completed, including those in Iowa, New Hampshire, Nevada, the US Virgin Islands, and now Haley's home state, trump has practically eliminated any chance for her to win the Republican nominee.
This week, a stubborn Haley—who previously served as Trump's UN ambassador—insisted that she would continue her campaign through "Super tuesday," which is scheduled for march 5 and involves Republican voting in 15 states and one US territory.
According to Edison Research, with only 2.5 percent of the anticipated vote cast, trump was up 63.8 percent to 34.8 percent.
In recent days, she has significantly up her criticism of trump, casting doubt on his mental stability and forewarning Americans that he would lose the general election in November.
However, there is little proof that Republican voters would support a candidate other than Trump.
About 39% of voters mentioned that matter, while just 33% stated that the economy was their main worry.
Voters' assessment of the state of the economy, which stands at 84%, indicates a serious vulnerability for Biden in November's general election.
Exit surveys, however, once more highlighted Trump's personal weaknesses. On saturday, over one-third of voters stated that if trump were found guilty of a crime, he would not be suitable to hold the office of president.
