Nikki Haley’s pitch is simple: She’s capable. She’s levelheaded. She gets things done. She’s not Donald Trump.

In a pool of anti-Trump also-rans whose challenges to the former Republican president have one by one fizzled out, Haley has run a surprisingly effective campaign, drawing oodles of money from establishment Republicans wary of the Trump circus, while coming shockingly close in the polls to the man who has spent the past year proving he has a stranglehold on the GOP base. She’s won the reluctant support of some prominent liberals, who view her as a vehicle to halt the march of Trump. All the while, she’s carefully left the door open for a possible future as vice president, deftly threading the needle between running as the antithesis of Trump and his possible future partner.

Haley appears as the Republican Party’s road not traveled in living, breathing form, a throwback to an older style of GOP politics that the 2016 election seemed to smash apart: when politicians weren’t borderline con artists selling conspiracy theories and plagued by outrageous scandals, when they seemed to be rooted in some semblance of decency and exuded basic, professional competence. “If you want something said, ask a man. If you want something done, ask a woman,” Haley memorably said four months ago, in a line typical of her political brand.
