When you re-wrote for Biden: "Now if Biden had said:

"I mean, you got the first mainstream African American running for president. He is articulate and bright and clean and a nice-looking guy","

I think you got it right. I think that was all he was trying to say. Who instead of He. Amazing to think of it.

But I think with the addition of Azizi's articles, above, and the rest of his baggage, he is going to sink with or without this little error.
