To be blunt, there is no practical reason for Haley to stay in the race at this point. She lost New Hampshire and South Carolina, which according to our modeling should be two of her very best states; as a result, she’s probably not going to win a single contest.

It also doesn’t make sense for Haley to stay in just in case the Supreme Court disqualifies Trump from the ballot. If that happens, other candidates like DeSantis will probably just jump back into the race, and they’ll be better aligned with where the Republican Party is these days. In fact, even as we sit here today, I’d honestly give DeSantis better odds than Haley of winning the GOP nomination, even as an inactive candidate.

Basically, there’s only one good reason for Haley to stay in at this point: principle. To give voice to an anti-Trump vision for the Republican Party. To be able to say “I told you so” if Trump loses in the fall. Because she sure isn’t going to be president.

Trump made a comment about how he would hold an election tomorrow if he could. It's true enough that plenty of countries hold elections on a less fixed schedule, but a candidate facing a number of serious charges related to election interference might not want to joke about that. But some of his other remarks, like his joke about how he doesn't mind talking about himself, reminded me of the feel of the 2016 campaign, and his ability to sometimes make voters laugh and feel in on the joke.

More race projections are coming in mere minutes after polls closed at 7 p.m. The Associated Press has already called the race for Trump based on their polling of voters, which showed Trump with a sizable enough lead to make the call. That call was echoed by other news organizations, including the New York Times, Wall Street Journal, and MSNBC. ABC News also projected Trump as the winner right as polls closed.

I tend to agree with you, Geoffrey. Haley is presenting a very different kind of agenda and policy positions than the more MAGA side of the Republican Party. And voters are noticing the difference.

In polling from YouGov/CBS News in February, likely South Carolina GOP primary voters were asked how they thought each candidate’s policies would impact the country if they were to win the presidency. Seventy-three percent said Trump’s policies would make them financially better off, while only 32 percent said the same of Haley. On immigration, 88 percent of voters said that Trump’s policies would make the U.S.-Mexico border more secure, compared to 53 percent who said the same of Haley’s policies.

The contrast is particularly stark on foreign policy: When asked how Haley’s policies would impact U.S. military involvement overseas, 41 percent said she would increase, 44 percent said she would not change and 15 percent said she would decrease military involvement. The reverse was true of what voters expected from Trump: a plurality of 47 percent thought Trump’s policies would decrease U.S. military involvement overseas, while 20 and 33 percent expected his policies to not change or to increase involvement, respectively.

So I’d buy an argument that Haley may be staying in to keep a more hawkish foreign policy position alive in the party, which makes sense, given her history as U.N. Ambassador.

Haley may have come up through South Carolina politics, but her old colleagues are mostly supporting Trump. Both of the state's senators, its governor, its lieutenant governor, its attorney general, its secretary of state, its treasurer, its agriculture commissioner and five of its six Republican U.S. representatives have endorsed Trump. In fact, many of them announced their endorsement quite early in the campaign, when Trump visited South Carolina in January 2023 — a coordinated show of early strength in a rival's home state. By contrast, Rep. Ralph Norman is the only major South Carolina politician who is supporting Haley.
