Answer: It's a coin flip whether Haley stays in until South Carolina
Haley said tonight that she's staying in the race, with an eye on the Feb. 24 GOP primary in her home state of South Carolina. Besides the caucuses in the U.S. Virgin Islands on Feb. 8, there won't be another Trump-Haley matchup until South Carolina because Haley didn't file for Nevada's Feb. 8 caucuses, which Trump was expected to easily win even before everyone else dropped out besides Haley. I'd make it a 50-50 proposition whether she stays in until South Carolina, however.
With the Palmetto State up next, I can see why Haley would like to stick around: Maybe she can win over voters in her home state, or something else could happen in the race to cause Trump's position to deteriorate. For instance, he's made some garbled, confused statements in recent days, including appearing to confuse Haley for Nancy Pelosi when talking about the Jan. 6 attack on the U.S. Capitol. Yet Haley also has to keep raising money to keep her campaign alive. That could be a challenge as GOP donors increasingly look ahead to the general election and her chances of defeating Trump look to be between slim and none. Moreover, if her position in South Carolina doesn't improve in the next couple weeks, she may not want to risk taking a big loss on her home turf.
