As a surrogate for black voters, Charlamagne is right for wanting Biden to give him more than hating Trump as a reason to vote for him. African Americans, really like all voters, want specifics.
Biden cannot rest his case on having been at President Barack Obama’s side for eight years as reason enough. Shouting “Barack” when you’re talking to black radio hosts or to black voters isn’t going to magically transfer African American support and votes to Biden.
Black employment is up and joblessness down during Trump’s tenure (although an argument can be made that it’s a track begun under Obama).
To win, Biden needs to replicate the movement that helped him win the South Carolina primary last February. Dangling the selection of a black female running mate and promising to support a study of reparations won’t be enough.
