Daniels does quote Nietzsche. To be noted, Nietzsche antedated Freud in his description of unconscious mental processes (although he did not use the word "unconscious'). Both he and Kierkegaard were early existentialists although that word was not invented until much later (Sarte).
Existentialists point out many big decisions are often little decisions made over a period of time. You are still responsible for all those little decisions and even for you decisions you don't think about. This means that Hillary and Bill aren't off the hook for their behavior even though it may not be conscious lying as we define it.
Yes, your and the author's points are well taken. But I do not believe Hillary lied about this in the way Daniels described. There is an assumption she knew perfectly well that the facts she relatede were untrue. I don't think so, and I do think for the reasons I gave.
