Trump's latest GOP primary target: A South Carolina congresswoman who worked for his 2016 campaign

Donald Trump on Wednesday night gave his “complete and total” endorsement to former state Rep. Katie Arrington’s day-old campaign to deny freshman Rep. Nancy Mace renomination in the June Republican primary for South Carolina’s 1st Congressional District, and he characteristically used the occasion to spew bile at the incumbent. Trump not-tweeted, “Katie Arrington is running against an absolutely terrible candidate, Congresswoman Nancy Mace, whose remarks and attitude have been devastating for her community, and not at all representative of the Republican Party to which she has been very disloyal.”

Trump previously backed Arrington’s successful 2018 primary campaign against then-Rep. Mark Sanford about three hours before polls closed, and his statement continued by trying to justify her subsequent general election loss to Democrat Joe Cunningham. The GOP leader noted that Arrington had been injured in a car wreck 10 days after the primary, saying, “Her automobile accident a number of years ago was devastating, and made it very difficult for her to campaign after having won the primary against another terrible candidate, ‘Mr. Argentina.’” It won’t surprise you to learn, though, that a whole lot more went into why Cunningham, who suspended his campaign after his opponent was hospitalized, went on to defeat Arrington in one of the biggest upsets of the cycle.

Mace, as The State’s Caitlin Byrd notes, spent most of the last several years as a Trump loyalist, and she even began working for his campaign in September of 2015 back when few gave him a chance. But that was before the new congresswoman, who won in 2020 by unseating Cunningham, was forced to barricade in her office during the Jan. 6 attack. “I can’t condone the rhetoric from yesterday, where people died and all the violence,” she said the next day, adding, “These were not protests. This was anarchy.” She went even further in her very first floor speech days later, saying of Trump, “I hold him accountable for the events that transpired.”

Still, Mace, unlike homestate colleague Tom Rice, refused to join the small group of Republicans that supported impeachment, and she stopped trying to pick fights with Trump afterwards. In a July profile in The Atlantic titled, “How a Rising Trump Critic Lost Her Nerve,” the congresswoman said that intra-party attacks on him were an “enormous division” for the GOP. “I just want to be done with that,” said Mace. “I want to move forward.” Since then she has occasionally picked fights with far-right party members like Georgia Rep. Marjorie Taylor Greene, but Mace has avoided messing with Trump directly.

Trump, though, very much isn’t done with her, and Mace seems to have decided that the best way to fight back is to emphasize Arrington’s loss. On Thursday, the incumbent posted a video shot across the street from Trump Tower where, after talking about her longtime Trump loyalty, she says, “If you want to lose this seat once again in a midterm election cycle to Democrats, then my opponent is more than qualified to do just that.” The GOP legislature did what it could to make sure that no one could lose this coastal South Carolina seat to Democrats by passing a map that extended Trump’s 2020 margin from 52-46 to 54-45, but that’s not going to stop Mace from arguing that Arrington is electoral Kryptonite.

While Trump, who The State says is planning to hold a rally in South Carolina as early as this month, has plenty of power to make the next several months miserable for Mace, the incumbent has the resources to defend herself: Mace raised $605,000 during the fourth quarter and ended December with $1.5 million on-hand. The congressman also earned a high-profile endorsement of her own earlier this week from Nikki Haley, who resigned as governor in 2017 to become Trump’s first ambassador to the United Nations. On the Democratic side, pediatrician Annie Andrews just reported raising almost half a million dollars in her first two months in the race.
