"I shouldn't have been such a wise guy. I shouldn't have been so cavalier," said Biden, speaking on a damage control call with black business leaders.

"I don't take it for granted at all and no one should have to vote for any party based on their race, religion or background. There are African Americans who think Trump is worth voting for. I don't think so and I'm prepared to put my record against his, that was the bottom line and it was really unfortunate, I shouldn't have been so cavalier."

No word on whether he thinks the black business leaders are "the first mainstream African-American(s) who is articulate and bright and clean" like he said of Obama in 2007.Joe Biden just massively insulted black voters - telling a popular black radio host on Friday that he 'ain't black' if he was still weighing whether to support Biden or Trump in the November election.
