COLUMBIA, South Carolina — Republican South Carolina Gov. Henry McMaster won his party’s nomination for a second full term Tuesday, while five Democratic gubernatorial candidates were vying for their party’s nomination. If McMaster wins the general election in November and completes the term, he will become the longest-serving governor in the state’s history. The governor defeated Harrison Musselwhite, a trucker and former businessman who said he was running to allow open carry of guns, prevent any government vaccine mandates and eliminate state income taxes. McMaster mostly let his governing do his campaigning, reminding voters how the state’s economy is booming and how he tried to carefully tailor COVID-19 restrictions when the pandemic started.
