The Democratic National Committee’s August 2026 decision to place South Carolina first on the 2028 primary calendar, with its January 22 contest emphasizing Black voters who form the state’s core Democratic electorate, has shaped early positioning. This structural factor sustains Kamala Harris’s leading share in trader pricing, while a fragmented field of governors and senators such as Jon Ossoff, Gavin Newsom, Raphael Warnock, and Cory Booker keeps probabilities clustered tightly among top names. No candidate has formally declared, and recent post-midterm gatherings of potential contenders have not yet produced clear momentum shifts. Traders appear to weigh name recognition, past South Carolina performance, and coalition-building against the long timeline and risk of late entrants altering the contest before the first votes.
