“Trump: Where do we go from here?”

It's not clear to me what you want this essay to say. At present, it appears to be mostly a testament to disorientation, which is certainly a feeling that you share with many people who have a longer experience with our politics than you. And it is perfectly in tune with the "noises off" in its doubt that whatever we were caring about before is still relevant in the present situation.

But to say this and no more is, for that very reason, to have in hand a sketch, rather than an essay. The question being asked is neither historical (how do we interpret this event in the context of what came before) nor political (what resources have we to struggle for what we wish to direct power to do). Probably, therefore, it's the wrong one.
