She’s a criminal.
Donald promised to appoint a special prosecutor.
Comey said she sent classified data.
You love her and dream of giving her tongue baths.
Nobody else on this forum does.
The fact that she has a defense other than “Yes, I am guilty.” does not prove that she cannot be prosecuted to anybody other than those who are in love with her like you are.
Most people would be prosecuted for what she did. She will probably skate, although I might end up surprised. The reason is pretty simple, she is hiding behind crimes of her subordinates and using a I-know-nothing defense. Although she sent plenty of classified emails, she didn't send anything "marked classified" except a couple emails which were marked (C) for confidential. That's because all of her underlings put in the minimal effort to strip classification markings from the emails they sent her. But a few got through with the (C). She forwarded some of them. She told the FBI she thought it was section C comes after A and B.
That's the reality. Almost anyone else who did that and used those lame excuses would be prosecuted, but she will not because she has too much power over the FBI and others.
Anyway you are missing the bigger point which is her prosecution (and subsequent acquittal) creates no political advantage whereas leaving the sword hanging over her head has political advantages. Spending time going after her would be stupid and Trump is not stupid.
