Principle is the only reason for Haley to stay in at this point
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.
