'Someone’s getting nervous': Republican says attack from MAGA super PAC proves 'Trump is scared'

A super PAC supporting former President Donald Trump's 2024 is running ads in New Hampshire attacking his top rival — who is relishing the attention.
In the first-in-the-nation primary state of New Hampshire, the Associated Press reports the Make America Great Again Inc. super PAC is running an ad attacking former UN ambassador Nikki Haley for her flip-flopping on support for a gas tax when she was governor of South Carolina.
"New Hampshire can’t afford Nikki 'High Tax' Haley," a narrator's voice-over is heard saying in the ad.

"Two days ago, Donald Trump denied our surge in New Hampshire existed. Now, he’s running a negative ad against me," Haley tweeted Monday night. "Someone’s getting nervous."
According to RealClearPolitics data, Haley has seen her polling jump drastically in the Granite State from the low single digits in September to more than 21% as of December 16. She's continued to out-perform her other non-Trump rivals in New Hampshire, leaving former New Jersey Governor Chris Christie and Florida Governor Ron DeSantis in the dust as her campaign continues to build up momentum. Haley campaign spokeswoman Olivia Perez Cubas said the latest attack ad proves that "Nikki Haley is surging and Trump is scared."
New Hampshire Republican Governor Chris Sununu — who has endorsed Haley's presidential campaign — echoed that sentiment in a recent interview. The four-term Granite State governor told CNN's Jake Tapper that Trump was "running scared" and trying to distract from his own failure to enact conservative policies during his four years in the White House.
"Clearly [Trump] knows momentum is on [Haley's] side. She has a ground game he doesn't have," Sununu said. "When he starts spending money on attacking someone directly, you know he's very nervous about losing... He's nervous his base is going to leave him at this point. That's why he gets so extreme in some of these speeches he's giving."
