Clyburn’s South Carolina power makes state pivotal for Democrats' White House hopes

Jim Clyburn’s influence in South Carolina has made the state more than a waypoint on the presidential calendar. It is a proving ground, and for Democrats chasing the White House, it remains one of the few places where a single endorsement, a single turnout pattern and a single local infrastructure can reshape a race.

Clyburn has represented South Carolina’s 6th Congressional District in the U.S. House since 1993, and his stature inside the party rests on more than longevity. He was the first Black politician from South Carolina elected to the House since Reconstruction, and he later became the first African American to serve multiple terms as House Majority Whip. That record has made him a central figure in the House Democratic Caucus and a gatekeeper whose support still carries weight far beyond Columbia.

South Carolina’s role in Democratic presidential politics grew sharper after the party moved the state to the front of its 2024 primary calendar. The decision reflected the clout of the state’s Black electorate, which has long defined the Democratic primary there. In recent presidential contests, Associated Press coverage described Black voters as a majority or roughly two-thirds of the electorate, making South Carolina the first major test of whether candidates can connect with Black Democrats before the race expands elsewhere.

Joe Biden’s 2020 victory showed how decisive that test can be. He won the South Carolina Democratic primary on Feb. 29, 2020, with 48.7% of the vote and 39 pledged delegates, his first victory of that campaign. Clyburn’s endorsement gave Biden crucial momentum, turning a late-breaking success into a viable path forward. For rivals such as Bernie Sanders, Hillary Clinton and Kirsten Gillibrand in past cycles, the state’s political terrain has made Clyburn’s annual fish fry a necessary stop, not a ceremonial one.

That influence now intersects with a different kind of pressure: whether democracy is being protected in more than name. Clyburn has continued to frame voting access as an urgent issue, including by helping reintroduce the Voter Empowerment Act. His office has said states adopted at least 94 laws making it harder to vote in the 11 years after Shelby County v. Holder. That is where the abstract warning about civic fatigue becomes concrete. Doing enough means defending registration systems, election administration and public confidence before a crisis forces the issue.

In South Carolina, the political lesson is plain. Presidential hopefuls still need Clyburn’s blessing, but they also need the voting system, and the trust around it, to work well enough for Black voters and every other constituency that decides who gets a say.
