The decision to position South Carolina as the first 2028 Democratic primary on January 22 has elevated the state's role, where Black voters form a core constituency and could shape early momentum. With no clear frontrunner nearly two years out, trader consensus reflects a fragmented field in which candidates such as Kamala Harris, Raphael Warnock, Jon Ossoff, J.B. Pritzker, and others hold low double-digit or single-digit implied probabilities. Recent visits by potential contenders to the state underscore efforts to build local support ahead of the contest. The wide spread of odds stems from the long timeline, absence of an incumbent, and uncertainty over which national figures will enter and how they will perform among key voting blocs. Polling trends, formal campaign launches, endorsements from South Carolina Democrats, and early fundraising in the state could narrow the field by creating separation among the top contenders.
