President Donald Trump's late May endorsement of Lieutenant Governor Pamela Evette has driven her to dominant positioning in the Republican primary for South Carolina governor ahead of the June 9 vote. As the incumbent lieutenant governor and recipient of prior backing from term-limited Governor Henry McMaster, Evette consolidated support among likely primary voters in a previously fragmented field that included Attorney General Alan Wilson, U.S. Representative Nancy Mace, U.S. Representative Ralph Norman, businessman Rom Reddy, and state Senator Josh Kimbrell. Pre-endorsement polling showed a tight contest with multiple candidates near 15-20 percent, but the high-profile alignment shifted trader assessments reflected in current market pricing. The primary outcome will determine the Republican nominee for the November general election in the solidly Republican state.
