President-elect Joseph R. Biden Jr. plans to name Jaime Harrison to lead the Democratic National Committee, according to two people with knowledge of the selection.
A former chairman of the South Carolina Democratic Party, Mr. Harrison became a national political star last year as he shattered fund-raising records in his race against Senator Lindsey Graham. While Mr. Harrison lost in November, drawing 44 percent of the vote to Mr. Graham’s 55 percent, he developed a broad bench of support across the party.
He is also well-known to staff and members of the D.N.C., a result of his work heading the South Carolina state party and a failed bid to become chairman of the committee in 2017. (Tom Perez, the outgoing D.N.C. chair, won that race but has opted against running for a second term.) Mr. Harrison has been championed by Representative Jim Clyburn of South Carolina, an influential Biden ally who helped the president-elect win the primary race in Mr. Clyburn’s home state.
His selection, on the heels of Democrats’ victories in Arizona and Georgia, reflects Mr. Biden’s longstanding desire for Democrats to compete in once-red states, a recognition that the party will never sustain an enduring congressional majority without making inroads across the Sun Belt.
