Republican Gov. Henry McMaster is seeking a second full term in office. As Lt. Gov., he succeeded Nikki Haley in early 2017, winning the 2018 election by 54% to 46%. While the winner will have an uphill battle in this deep red state, the Democratic primary will be interesting to watch. It features former U.S. Rep. Joe Cunningham (SC-01) and State Rep. Mia McLeod. As there are three other candidates on the ballot, a June 28 runoff between these two is possible.
These primaries will be conducted using redistricted boundaries. Little general election competition is likely; Republicans are expected to hold their 6-1 edge in the delegation.
However, there are two Republican primaries worth watching, as incumbents that have run afoul of Donald Trump try to win renomination.
District 1: Nancy Mace is seeking a 2nd term. She earned Trump's enmity by criticizing the January 6 riots and then voting to certify the 2020 election. The former president has endorsed her opponent, former State Rep. Katie Arrington. This is Arrington's second campaign here, she was the 2018 nominee, losing to Democrat Joe Cunningham. A third candidate, Lynz Piper-Loomis withdrew during a late May debate, endorsing Arrington. However, she remains on the ballot, meaning a June 28 runoff between Mace and Arrington can't be entirely ruled out.
District 7: Tom Rice is seeking a 6th term. One of ten Republicans that voted to impeach Trump in January 2021, he has come under attack from the former president, who has endorsed State Rep. Russell Fry. For his part, Rice is doubling down on his anti-Trump position as the primary draws near. With seven total candidates on the ballot, a June 28 runoff between Rice and Fry seems the most likely outcome.
