It is very clear that their plan has gone to complete shit. The idea was to use Biden to coast Harris in and control her from the shadows. Except....
She is utterly incompetent on every level. She is woefully underqualified and is a charisma black hole. An empty suit needs to be an expensive looking suit, not a fucking garbage bag. And that's what Harris is. She can't maintain proper control, cannot lead and is clear she is unfit for office.
The problem that they have is that Biden is deteriorating much faster than they anticipated. I mean, he's fucking 78 and showing clear signs of dementia. The president, no matter how handled, is an extraordinarily stressful job that ages you. Sometimes decades. Stress adds to inflammation, which worsens dementia.
They were probably banking on Harris doing most of the heavy lifting and appearances, but she can't even handle soft-ball questions without getting defensive. She is loathed. The democrats put themselves in an awful position: they can't have Biden in forever and they can't really tell when he's going to fold in on himself. Eventually the drugs they're pumping in him will no longer have an effect and the words he says gets us (or them) into trouble. And at the same time, Harris has shown to be completely inadequate and unlikeable as his replacement. The only benefit she offers is that she's not a decaying corpse. Which is to say, not one for the dems at all. They need someone to advance their agenda, and Harris isn't it. She can't even mediate. A charisma black whole combined with a narcissistic ego along with chronic incompetence is....well, fatal. I don't know what the fuck they expected, she scored 1% in her own fucking state. And they CERTAINLY can't replace Biden, then replace Harris. Jesus. The optics on that is death.
So that is to say the Dems are between a rock and a hard place with no easy out. But fuck them, they did it to themselves because of their own greed and ego. Too bad they fucked everyone else along with them. Fucking neo-liberal scum.
