I don’t think Biden would be out in 6 months. Rather I think he would be maintained as the “president” for so long as he can say one or two recognizable words and with digital enhancement and digital imaging now almost perfected he can be brought back to apparent life and good health for the rest of his term during which the nation will be run by a politburo that gradually will be weeded through until one supreme General Secretary is calling all the shots but officially will only be an Advisor to the President until the next election which will be run according to newly emplaced Democrat devised rules.
The issue they have is can Demented Joe actually win? It’s one thing to speculate how he’d do as president, but he’s got to beat Trump, first. I think he’s through as soon as Trump shreds him in the debates.
So they either have Joe lose to Trump, Joe out before the General election and someone other than Bernie in his place, but then the party gets tore up by Burnie Bros, or let Bernie take the loss.
Hard to see there winning combination in all this. Mike Obama does not wanted to be tainted with a loss to Trump.
I’d say it’s possible to throw in a failed Hillary, and once and for all ruin her, leaving the Obama’s with 2024 exclusively their own.
