Trump on Haley: 'I don't care if she stays in' the race

STORY: The former U.S. president and the former South Carolina governor made their final pitches to voters in what became a two-person race after Ron DeSantis, the Florida governor once seen as the party's best bet to take on Trump, dropped out and endorsed Trump.

Polls show Trump with a wide lead over Haley, who needs a victory or a strong second place showing in New Hampshire to carry her to the next nominating contest in her home state of South Carolina, where Trump is also dominant in the polls.
