The only reason it is intertwined with the Democrats is because they (the Democrats) favor big government (i.e., the Deep State).
Because Trump and MAGA want limited government, they are THE existential enemy of the Deep State.
As an aside, now that the FBI has been caught in a crime with a money trail, who is going to prosecute them?
The Deep State is a monster...a beast. It is not just above the law. It IS the law.
Bureaucracies exist for no other purpose than to perpetuate themselves.
