Former US President Donald Trump cruised to a decisive victory on Saturday in the South Carolina Republican primary, blitzing rival Nikki Haley in her home state. The margin of victory was not immediately clear but it was expected to be significant, with major US networks calling the race within seconds of the polls closing.

“We expected this, but not this soon,” Trump said in Columbia, S.C., shortly after his victory was announced. He said the Republican Party was “more united than ever before.”

While Haley repeatedly questioned the 77-year-old former president’s mental fitness and warned another Trump presidency would bring “chaos,” her efforts appeared to do little to damage his standing among Republicans.

Haley, a popular governor of South Carolina in the 2010s and the only woman to have entered the Republican contest, was looking to outperform expectations in her own backyard. But she was never able to compete in a battleground that preferred Trump’s brand of “America first” and personal grievance over the four indictments and multiple civil lawsuits he faces.

Despite losing in her home state, former South Carolina Gov. Nikki Haley is not giving up on her campaign. According to her campaign manager Betsy Ankney, she is set to visit Michigan and eight other states that will vote on Super Tuesday in the next 10 days.

Trump had already won Iowa by 30 points and New Hampshire by 10, while a dispute in Nevada led to the real estate tycoon running unopposed in the official contest.
