Florida Governor Ron DeSantis has suspended his Republican presidential campaign, ending his 2024 White House bid just before the New Hampshire primary while endorsing his bitter rival Donald Trump.
The timing of DeSantis’ announcement escalates the pressure on former UN ambassador Nikki Haley, as the only major candidate left in the Republican nomination fight, to win New Hampshire’s first-in-the-nation primary on Tuesday.
Trump’s Republican foes finally have the one-on-one contest they have sought for months.
“It’s clear to me that a majority of Republican primary voters want to give Donald Trump another chance,” DeSantis said in a video announcing his decision to drop out of the race which he posted on X.
DeSantis also jabbed Haley, long his closest competition for second place in the primary race, saying Republicans “can’t go back to the old Republican guard of yesteryear, a repackaged form of warmed-over corporatism that Nikki Haley represents”.
Haley was campaigning in Seabrook, New Hampshire, on Sunday when DeSantis announced his decision.
“He ran a great race, he’s been a good governor, and we wish him well,” she told a room packed with supporters and media.
“Having said that, it’s now one fella and one lady left.”
DeSantis’ decision, while not surprising given his 30-point blowout loss last week in Iowa, marks the end of an extraordinary decline for a high-profile governor once thought to be a legitimate threat to Trump’s supremacy in the Republican Party.
He entered the 2024 presidential contest with major advantages in his quest to take on Trump, and early primary polls suggested DeSantis was in a strong position to do just that.
He and his allies amassed a political fortune well in excess of $US130 million ($A152 million), and he boasted a significant legislative record on issues important to many conservatives such as abortion and the teaching of race and gender issues in schools.
Such advantages did not survive the reality of presidential politics in 2024.
