South Carolina's confirmation as the first 2028 Democratic presidential primary on January 22 has elevated its importance due to the state's large Black electorate, shaping early positioning among potential contenders. Trader consensus reflects a competitive field, with Kamala Harris holding the highest implied probability at 28 percent amid her established support in the state, followed closely by Jon Ossoff, Gavin Newsom, Raphael Warnock, and Cory Booker. Frequent visits by these figures and others like Andy Beshear, Ro Khanna, and J.B. Pritzker for midterm campaigning have kept momentum fluid without formal declarations. Recent polling shows Harris ahead nationally but with softening numbers in some surveys, while the absence of major endorsements or policy shifts leaves room for separation through fundraising, coalition building among key voting blocs, or developments before the primary window.
