Donald Trump wants to make South Carolina the end of the road for Nikki Haley in their battle for the Republican nomination. Haley aims to survive and take their fight into the multistate Super Tuesday contest in March.

Opinion polls show the former U.S. president with a clear advantage in South Carolina ahead of the state’s primary on Saturday, despite the fact that Haley served as its governor for six years.

Haley’s rationale for staying in the race will become harder to see if she’s buried by Trump in South Carolina, after also losing to him in Iowa and New Hampshire. The pressure for her to drop out will come fast and hard.

But Haley, who served as ambassador to the United Nations under Trump, may view the race as being about more than her. She speaks now for the bloc of Republican voters who can’t abide Trump.
