Maybe Uncle Joe can be Kamilla's V.P. He's got the experience and it is a largely ceremonial job which Joe may can handle even with early stage dementia.
The Democrats have clear rules these days, even if they deny it.
1) One is that a White Boy nominee must pick a Black Woman V.P.
2) The corollary is that a Black Woman nominee must pick a White Boy V.P....doesn't have to also be gay, but it would help, if you can find one who is not a self-righteous religious hypocrite like that little turd from South Bend--Mayor Pete--who so obviously belongs on the cover of Mad Magazine that Mad went out of business when Buttgig wouldn't agree to it.
As to Rule No. 1, A Straight White Boy with early stage dementia (and who was a dumbass before he got old and frail) must pick for his V.P. a Black Woman.
Exceptions (waivors) can be granted by the Grievance Factions which make up the Democratic Party. The Woman's Grievance Faction would be fine with Pocahontas as V.P.; the Black Grievance Faction would be fine with Spartacus; the Hispanic Grievance Faction would be fine with Castro...but any one of those three factions can only piss off the other two....and all three are already pissed off because, as a general rule you, have to be an Unhappy Person to be a Socialist/Democrat to begin with.
What to do, Joe?
I don't think he gets a choice. He's got a year and a half for Frailty and Diminished Mental Capacity to just get worse. He's not going to be able to hide it, especially when even the slow-witted Democrats saw him as a Dumb-Ass to begin with.
Straight White Boy Socialist Bernie "The Bern" Sanders is done. Every other Democratic Candidate has now adopted the Bern's platform of nearly pure Socialism...he is the brains and the soul of the Party...but he cannot be the nominee because he told the truth---he admitted he was a Socialist. You have to lie to the American people, and even lie to yourself, to be a Democratic candidate, and all the other candidates are Liars. Socialist, but they lie and say they are not.
My money would be on Kamala Harris because that is who the New York Media is backing, and the New York Media is nothing if not the Pravda of the Globalist-Elitist Faction of the Socialist Democratic Party--the ones who actually run the other Grievance Factions, even if the others don't realize it.
The White Boy she needs to pick really must be able to deliver Texas or the Mid-West and PA. But the only Texas White Boy available is that truly empty suit and fraud--"Beto". Empty Suit is too kind---Spastic Whack Job is more definitive. Kamala has to pick a White Boy from the Heartland, but it won't be this witless asshole.
Just my opinion of course. Thanks if you read this far. I likely wouldn't have made it.
