Republican presidential candidate Nikki Haley is banking on victory in New Hampshire to carry her through her home base of South Carolina and the rest of the 2024 race.

New Hampshire is Haley’s Holy Grail due to the large share of independents who could pull the lever for her in the 39% unaffiliated voter state.

Polling numbers show her rising in the Granite State, even coming within four percentage points of Donald Trump in one survey.

But the “momentum” Haley’s camp is hoping for could be fleeting.

Per RealClearPolitics’ average, Haley is polling at 21.8% in South Carolina compared to Trump’s 52%, and still more than 20 points behind the former president in the Granite State.

The former ambassador to the UN must also overcome other hurdles to capture the nomination.

In Nevada, which votes in early February, Haley is the sole top GOP candidate competing in the Feb. 6 primary, and is not eligible to earn any delegates.

All other White House hopefuls are competing in the caucuses, which are run by the state Republican party and will be held two days later.

Haley’s likely “win” in the Nevada primary could give her easy media coverage, but the results of that election will only be publicized after the caucuses, potentially giving her no bump at all.

Haley’s New Hampshire-centric strategy has become clearer in recent days, with the candidate telling voters in Milford they can “correct” the Iowa outcome and GOP Gov. Chris Sununu predicting she would win in his state.

“You know Iowa starts it. You know that you correct it … you know that my sweet state of South Carolina brings it home,” Haley said at the Wednesday night town hall.

She defended her comments in an Iowa town hall Thursday night in response to jeers from the audience, saying she was having “fun” and trying to inspire “banter” between the early states.

The former South Carolina governor has been ambiguous about her target finish in both states, only saying she wants to be the primary challenger to Trump.

Sununu offered the clearest prediction from her camp on Wednesday, guaranteeing she will defeat Trump in New Hampshire and deliver a “strong second” in Iowa.

Haley’s campaign told The Post that it sees the Granite State race as a straight showdown against Trump.

“This is a two-person race between Donald Trump and Nikki Haley. Trump is spending millions in attack ads against Nikki because he’s scared. Nikki is putting in the work, shaking every hand and answering every question. We’re excited to keep building off our momentum,” Haley spokesperson AnnMarie Graham-Barnes told The Post.

The super PAC backing Trump, MAGA Inc., recently released an ad in New Hampshire targeting Haley over her stance on the federal gas tax. Trump’s campaign also released an ad on her immigration policies.

Haley has also been campaigning heavily in Iowa and has seen some movement in the polls — but not to the degree of New Hampshire.

Her sprint for the caucuses was boosted by a November endorsement from the Americans for Prosperity Foundation, a Charles Koch-funded organization with aggressive grassroots capabilities. Since then, the surrogates have worked to convince voters to choose Haley, but have been playing catch-up to Florida Gov. Ron DeSantis, who had put his primary focus on Iowa earlier in the fall.

DeSantis, who has been slipping in the polls, moved a large portion of his staff to Des Moines and dedicating time to visiting each of the state’s 99 counties, a feat known as the “Full Grassley,” in reference to the long-serving Republican senator.

Haley’s focus has been more on all three of Iowa, New Hampshire and South Carolina, compared to DeSantis’ “Iowa-or-bust” strategy, her campaign previously told The Post.

Haley will continue to campaign in Iowa and New Hampshire before the early voters make their decisions on Jan. 15 and Jan. 23, respectively. She plans to go to the Hawkeye State with Sununu on Saturday to hit three cities with the governor.

She’s also slated to participate in a debate with DeSantis on Jan. 10 in Iowa, days before the caucuses, and will likely debate him again in New Hampshire on Jan. 18 and 21.

Haley’s campaign previously told The Post it expects to win the South Carolina primary on Feb. 24.

Win or lose, the result will be monumental for Haley, who was atwo-term governor in the state. Top elected officials, including Gov. Henry McMaster and US Sen. Lindsey Graham (R-SC), have backed Trump.

Sen. Tim Scott (R-SC), who clashed with Haley on the campaign trail before dropping out of the 2024 race, has yet to make an endorsement.

An Emerson College poll released Friday showed Haley polling 29 points behind Trump, 54% to 25%.

Performing well in both Iowa and New Hampshire will be the ticket if Haley is to have any hope in her home state, South Carolina-based GOP strategist Dave Wilson told The Post.

“Nikki Haley is going to have to show that she can come in first or a very solid second in Iowa and New Hampshire to come into South Carolina with enough momentum to surpass Donald Trump,” Wilson said.

“His lead is solidly 25 points-plus, and it is going to take a lot of momentum and traction for Haley to surpass that in a state where a plurality wins all the delegates.”
