Recent polling showing a statewide tie between Republican Darline Graham Nordone and Democrat Annie Andrews has tightened the overall race, yet traders assign Darline Graham Nordone an 87% implied probability of carrying Greenville County. This positioning reflects the county’s Republican-leaning electorate, its performance in the August GOP primary runoff, and consistent historical margins in upstate South Carolina despite Andrews gaining ground among independents and some Republican voters in regional crosstabs. Nordone’s Trump endorsement, party infrastructure, and focus on economic and security issues continue to underpin strong local support heading into the November 3 election, while Andrews’ advantages remain more pronounced in other parts of the state.
