I think the biggest promise made was to see Hillary in prison, which would have to include all of the deep state. This is why I voted for him. I am grateful for four years of a great economy and a decent section of border wall built (that will probably just be torn down if Biden is in) and everything else he did, but his main promise was to destroy the deep state. That remains undone, and that remains the only thing that can undo everything else he has done. I remain hopeful that he will fulfil this promise as well, but time is growing very short.
