President Donald Trump’s endorsement of Lieutenant Governor Pamela Evette on May 29, 2026, has consolidated Republican primary voter support ahead of the June 9 contest, elevating her to a dominant position in the race to succeed term-limited Governor Henry McMaster. As the incumbent lieutenant governor with prior business experience and alignment on state tax and regulatory priorities, Evette has drawn endorsements and fundraising advantages that have widened her lead in recent polling. The remaining candidates, including Attorney General Alan Wilson and U.S. Representative Nancy Mace, trail significantly and have not consolidated sufficient support to force a runoff or shift momentum. Late developments such as unexpected turnout patterns among key voting blocs or unforeseen campaign events could still alter the outcome before primary ballots are cast.
