Biden's former record is actually enough to make African Americans question a vote for him.
It is not necessary dissect a statement he made [obviously out of jest] into being 'condescension' because you don't like Biden or because you don't like his record.
A Black/African American [bi-racial] politically astute Harvard educated lawyer, Constitutional Law Professor and former Senator, chose Biden as his Vice President, former political record and all.
Biden is really a republican in democrat clothing, just like Amy Klobuchar, whom he's probably already chosen to be his running mate, since he clearly 'dissed' Stacy Abrams, whom he had obviously lead to believe that he would be announcing her as his running mate on the Jake Tapper show, only for her to find out the opposite was true in such a dirty way.
For this, Biden most likely can kiss at least half the Black vote goodbye, which means that once again, Trump will be in the White House, because of democrats' belief that they can 'diss' Black people and still get elected. [Democrats didn't learn from the last presidential election.]
What African Americans should be worried about is the Racist, Fascist, Nazi dictatorship that is set to unfold upon the re-election of Donald J. Trump.
