A runoff between the top two finishers is all but assured, as candidates in the Palmetto State must attain more than 50 percent of the vote. Polling in the race has varied, but the top three candidates in the race remain steady: Sen. Darline Graham Nordone, Rep. Russell Fry, and Rep. Ralph Norman. Also in the race are former Rep. Mark Sanford, Duke Buckner, Danny Ford, Mark Lynch, Mark McBride, Glenda Parker, and Samuel Shepherd. Campaign ad spending by aligned super PACs reached at least $4.2 million according to AdImpact, most of which has been in support of Fry and Graham Nordone. Palmetto Leadership Fund has spent over $1 million on Fry’s behalf, with a similar amount in support of the Trump-endorsed Graham Nordone by a Palmetto Action and Security is Strength PAC.
