She would need to continue dominating debates; she would need to not fade or completely lose it when Mr. Trump turns a real attack on her; and more than anything she would need a substantive critique, even if gently delivered, of Mr. Trump to feel true and land with people. Maybe it’s that idea of putting things back together, which she did not repeat in New Hampshire last week, that has the virtue of matching Ms. Haley’s vibe, while also responding to the widespread feeling the earth is falling apart. A win in Iowa or New Hampshire for Ms. Haley would reset the entire primary.
This, or some array of similar conditions, still seems very unlikely. But it’s a lot less unlikely than it was six months ago. And it’s more or less what happened, on a smaller scale, for Ms. Haley in 2004 and 2010 when she ran for the South Carolina Legislature and then for governor. Those campaigns started off seeming ridiculous and involved Ms. Haley, holding doughnuts, knocking on doors for votes (though that is what it looks like when someone runs against a longtime incumbent). Then those campaigns gradually caught on, brought in such disparate backers as Sarah Palin and Mitt Romney, and — though she didn’t mention it when she talked about those campaigns last week — when they became competitive, the campaigns ended in brutal attacks on her, and Haley wins.
Last winter, when she announced, a lot of people considered her campaign a waste of time. Even more, they argued that her glossy corporateness was out of touch with today’s G.O.P.; that she must be running for vice president. That response likely derived from the ridiculous period after Jan. 6, when Ms. Haley criticized Mr. Trump harshly, then seemed to dial it back. Part of it is the smooth, pain-free way Ms. Haley entered and extricated herself from the Trump administration, after criticizing him in 2016 and endorsing Marco Rubio. Some of it’s the fluid way she talks and the clothes, too, even if they likely harken back to a not-Ivy-League facet of her life: growing up working in a clothing store in the small-town South. This picture of Ms. Haley culminated in Vivek Ramaswamy congratulating her on her future on the Raytheon board.
But the full Haley story has a lot of brutal moments in it; hers is not a soft career. She really brings something out in people: guys who used slurs to describe her; the former Democratic Party official who in 2013 compared her to Eva Braun and said she should go back where she came from, then clarified to say he meant “being an accountant in her parents’ dress shop”; Rex Tillerson, who used a sexist term to describe her, according to the writer Tim Alberta. There have been people who have said she lies about her religion. The political consultant Stuart Stevens recently told The New Yorker that the only difference between Ms. Haley and Marjorie Taylor Greene was “purely aesthetic.”
In 2004, when she was running for the state legislature, people sent racist mailers about her parents, who had lived in South Carolina for 30 years, had painted an American flag on the ceiling of their clothing store and had organized a local international night and science programs in their small town. Except voters in the district felt as if they knew her. “By that point, Nikki had already met every single voter who got those mailers,” the former state party chairman Katon Dawson told Mr. Alberta. “They all had talked to her. It made a lot of those people angry on her behalf.”
