Not saying I agree with this, but a reasonable position is that Clinton lied about things that could have affected National Security. There were classified documents on her personal server despite her sworn testimony that there weren't.
I thought Trump's lies, and unwillingness to backtrack on them when they were pointed out, was disturbing. Almost sociopathic. But now I'm trying to wrap my mind around the fact that the whole thing might have been an act, an act which achieved its goal. If that IS the case, now that he's achieved his goal, maybe the act will change. We can only hope.
