From the article, the author is mystified as to why Hillary would engage in the corrupt practices we know about, when they were so obviously going to be discovered.
He can't understand it, and so speculates:
Because none of this adds up to a coherent explanation, I believe we are still in the dark about a hidden bombshell. There must be a secret Unholy Grail that explains her self-destructive behavior of stonewalling and lying.
Actually, I doubt it. I think the corruption we see is just the same as the corruption we haven't seen yet -- the corruption of a grasping, greedy woman who has never been held accountable in the past and, with good reason, has no expectation of being held accountable now or in the future.
There's no huge, different thing. There's no lurking bombshell (as if the current corruption weren't bombshell enough).
It's just garden variety corruption -- yet another example of the banality of evil.
