"Those running the show" are not a unified, monolithic group. There are factions in conflict over goals and methods. And the factions have made serious mistakes in many of their plans. The appointment of Kamala Harris as Vice President is an example.
Joe Biden's visible decline into senility and the prospect of his unpredictable death due stroke or aneurism represent a looming crisis for the oligarchs. They must replace him while they can still maintain control of the succession.
I believe somebody in the cabal has panicked and jumped the starting gun with all these revelations about Biden's illegal possession of classified documents. They don't need to force him out. He will do whatever they tell him to do. He always has.
This looks to me like the people who backed Harris have been losing the internal arguments of the cabal and are trying to prematurely force a situation where they can get their preferred candidates in as the replacement team. I do not see the indicators for how they will get rid of Harris, but I am sure the replacement team does not include her.
Coups have consequences.
Easiest way to replace Harris (with either Newsome or Buttigett) is a (failed) assassination attempt on her. By a white MAGA hat redneck “Christian “ using an AR 15.
And then white redneck is immediately killed Jack Ruby style by their instantly heroic FBI.
