The South Carolina GOP primary will mostly be devoid of drama. Still, all eyes are on the 1st Congressional District, where Rep. Nancy Mace (R-SC) seeks the renomination against Donald Trump-endorsed Katie Arrington, in yet another test of the former president’s influence within the party.

Arrington won a shocking primary win over Mark Sanford in 2018, losing to Democrat Joe Cunningham in the general election, the first time a Republican lost that seat in nearly 40 years.
