I’ve said this over and over again, (…) Joe Biden was not picked in 2020 because he was the only person that could beat Trump. He was picked because he was the only person that could beat Bernie Sanders, rightly or wrongly. … That conclusion was made, okay? “Oh my gosh, coming out of Nevada, Bernie Sanders is going to be the nominee!” And people, just like they are now, said, “Ahhh, I don’t think that’s going to work,” so they were looking for an alternative.

I was an elite that supported (Biden) in 2020, (…) And said that we should do everything we possibly could do to advantage (Biden) against Bernie Sanders, because I thought Bernie Sanders’ politics were detrimental to the party and to the country.

This seems to be the gist of the article.
