NORTH CHARLESTON, S.C. — Nikki Haley has ramped up her criticism of Donald Trump over the course of the 2024 presidential campaign. But she’s taking the attacks and the back-and-forth to a new level as she digs into a month of campaigning in South Carolina before the state’s Feb. 24 primary.

She was greeted in her home state by about a dozen Trump supporters protesting outside her Wednesday-night rally here. And Haley gave back as good as she was getting, dispensing with her usual stump speech introduction to go directly after the former president at the top of her own remarks on Wednesday.

“Bring it, Donald,” she said, as she challenged the former president to a debate.

She brought up Trump’s focus on her in his victory speech on the night of the New Hampshire primary, calling it a “temper tantrum.”

“I know that’s what he does when he is threatened, and he should feel threatened, without a doubt,” she said, as the crowd of hundreds cheered.

In another escalation, Haley — who says her campaign raised $1 million in online and small-dollar donations in the 24 hours after her speech in New Hampshire on Tuesday night — fundraised off of Trump’s attacks for the first time Thursday.

In response to the former president’s threat on Truth Social that anyone who donates to Haley would be “be permanently barred from the MAGA camp,” the Haley campaign began selling T-shirts that said “BARRED. PERMANENTLY.”

Despite growing calls to drop out and have the Republican Party coalesce around Trump after his 11-point win over Haley in Tuesday’s New Hampshire primary, Haley indicated her intention to stay in the race, saying, “Americans deserve better than what they have in these two options.”

“Listen, we’ve only had two states that have voted,” she said Wednesday. “We got 48 more that deserve to vote.”

The Haley campaign began running ads in South Carolina on Wednesday, and its aligned super PAC, SFA Fund Inc., will be starting a million-dollar ad buy in the state next week, according to the group’s spokesperson. Both the campaign and super PAC have indicated their intention to stay in beyond Haley’s home-state primary, expressing optimism for Haley’s chances in Michigan’s Feb. 27 primary and some of the 16 primaries on Super Tuesday, March 5. (Michigan Republicans have a hybrid system with both a primary and a March 2 caucus, with more delegates at stake at the caucus.)

On Thursday, SFA Fund announced that it raised over $50 million in the last six months of 2023, a hefty sum that could well finance an extended campaign.
