Nikki Haley lost the New Hampshire primary but found a cause: getting under Donald Trump’s not exactly rhinoceros-thick skin. The story of the Republican primary campaign in the days since Trump’s victory has been one where the victor acts like a sore loser and the likely loser loosens up, goads her stronger rival and finds a pool of small-dollar donors to keep her in the race.

Haley’s turn toward mockery and confrontation has created modest excitement in the disillusioned world of NeverTrump punditry. Maybe the remaining non-Trump Republican is giving up on being vice president or winning some future G.O.P. primary campaign. Maybe she’s ready to make Trump’s unfitness her exclusive theme. Maybe, as The Dispatch’s Nick Catoggio speculates, by needling and attacking and bringing out Trump’s worst behavior, she can even bring about the long-awaited Republican crackup that would finally defeat Trump on the scale that he deserves.

I don’t think this hope makes a lot of sense. The idea that there exists some form of elite Republican denunciation, combined with egregious Trumpian misbehavior, that could shatter the G.O.P. coalition and send him to a Barry Goldwater or George McGovern-style defeat, seemed plausible enough eight years ago. It’s what I expected and what Republicans deserved.

But I should have heeded the wisdom of Bill Munny in Clint Eastwood’s “Unforgiven”: “Deserve’s got nothing to do with it.” Because since then we’ve seen all kinds of terrible behavior, coupled with attempted repudiations from all sorts of Republicans, including Trump’s own aides and cabinet appointees. And yet the rule has held: Ask people if they like Trump and majorities do not, but put Trump up against the current Democratic Party, and he becomes a viable candidate for president.

Maybe Haley is the right figure to change that. But she has nowhere near the pre-Trump fame of a Mitt Romney or the ideological credibility of a Liz Cheney. And based on what we saw from Chris Christie’s campaign, a pure repudiate-Trump candidacy is only likely to enhance Trump’s margins in the remaining primaries, emphasizing Haley’s hopelessness rather than her gumption.

Moreover, wouldn’t there be something a little bit strange, after two consecutive primary campaigns in which Republicans desperately competed for a chance to face off with Trump one-on-one, for the winner of that prize to immediately give up on winning any more supporters? Haley’s consolidation of gentry Republicans succeeded in boxing out Ron DeSantis’s attempt to build a larger non-Trump coalition. Is she really not even going to attempt to build a larger coalition of her own?
