There was a time when you could argue the issue was, as Steve Bannon once intimated, that Trump is easily duped. But the buck stops with him in the end.

Almost every excuse for Trump centers around the idea that he's the biggest retard on this planet and doesn't know any better. The other excuse is that he's only pretending to be retarded and that it's all 4d chess (have you even read The Art of War!?)
