My theory is that they will once again try to stack his administration with Neocons and Goldman-Sachs employees.
If I were Trump I would fire every appointed official. Then instead of trying to fill the positions, I would leave them vacant and ignore any regulations or rulings that came from the departments as having no official leader.
Focus on closing the border with military troops if necessary, turning down the heat on foreign wars, and giving domestic policy over to gridlock.
It was obvious the last time.
My take—use every means and invent a few more to steal the election and start WW III to cover it up. Get Trump in a shooting war, that people will hate, start anti-war, anti-draft movements to unseat or force Trump to do a Nixon. Don’t dig too deep or the truth about a bunch of assassinations will come out.
That would make it impossible for the Trump Administration to undo a ton of the regulations implemented by Biden and the Democrats. Courts would continue to enforce them because they'd still be part of the Code of Federal Regulations. And trying to remove them one at a time by legislation would be stopped by a Dem filibuster.
And if civil service laws prevent their firings, he should start "investigations" of each individual and "suspend" them pending its conclusion (it would never conclude) and cancel their RFID clearance cards to the buildings. If they sue, fight the suits with the full power of the DOJ and refuse any court orders for 4 years, citing Executive Privilege.
