Joe Biden secured a victory in the Democratic primary in 2020 after Rep. Jim Clyburn threw his support, and that of his Black constituents in South Carolina, behind the candidate. Black voters – and young Black voters in particular – appear to be much less enthusiastic about Biden these days. They’re the most unenthusiastic they’ve been about a Democratic president in decades. Republicans have also intentionally thrown roadblocks in front of efforts to mobilize the full power of the Black vote: think gerrymandering, voter ID laws and the like.
