Evil has a way of chewing up and spitting out the people it uses once they become useless for it. This is especially true when they are egregiously empty channels like Trump. During the time Evil uses them, they have this ability to cast spells, but at a certain point the magic stops working. They keep using the same incantations, but they have no effect.
This is why Trump keeps going to the 2016 Book of Spells. It’s his attempt to use the old magic even though he’s all but lost his power to enchant. The people who were spellbound are beginning to snap out of it, and when they do, they see him for the cipher that he truly is and always has been. I don't know that Trump has completely lost his ability to enchant yet, but I'm hopeful we're in the beginning stages of it.
One sign will be if the rats start abandoning ship in significant numbers. Once the sycophants around him no longer have any reason to fear him, they will do whatever it takes to save their own skins. Keep an eye on Pence.
I predict nothing except that the unexpected lies before us. X, Y, and Z will happen in the next six months; we just don't know what they will be.
