Is Trump being held hostage by his family?

in reality their marionette?
It occurred to me as the past week unfolded in Cleveland that every time Trump appeared he was surrounded by his family.
Like a cocoon he stepped into.
Then it occurred to me that perhaps Trump is simply their pawn to break the GOP and set the foundation for their take over of the world.

Well, not by his family, who seem to be just lesser versions of himself. But I do think the powers that be (PTB) are licking their chops at having Trump as POTUS. As Carter said, he’s malleable. The PTB will easily be able to steer him in whatever direction they need.
