I hope you are right but I do not thinks so.
Not going to be Biden, old white guy, too many skeletons, not progressive enough, he will be taken apart by his own party and the media.
And Adams is too big of a reach.
IMO Kamala Harris, AA, wo man, Senator in big Dem state, a former high level prosecutor, and yes she can be persuasive, even charming.
I think the Clinton-Soros-0Bama machine will get behind her when the time is right, and the media-press-Hollywood-academia-Facebook-Twitter-YouTube-Google propaganda will make her a star.
