Unfortunately it's not that simple. First off, there is nothing wrong with her using a private email address on a private server. Previous Sec. of States have had them. The problem is that her emails related to her position as Sec. of State are a matter of public record. She was comingling them on a private server with her private email. When she received requests from Congress to turn over emails regarding Bengazi, she made the determination of which ones she would turn over and which ones were of a "personal nature" and not subject to public disclosure. So she only released a very few. After more pressure she then was forced to release over 30,000 emails to the State Department. Before those emails can then be released for public viewing, the US Inspector General's Office reviews the emails to redact any classified or other protected information. In a 2% sample size of emails that the Inspector General reviewed during this investigation of the 30,000 emails, there are 4 that were listed with top secret/SCI level security. That has now opened up the criminal aspect of this issue.
If you are a government employee and you propagate the removal or transfer of classified information from a secure holding platform to one that is unsecure then you have violated the Espionage Act. That is a felony crime. Hillary is guilty of this by receiving classified emails on her un-encrypted server. If the sample size is consistent for the entire block of 30,000 emails she has released then she could be looking at 200-300 counts of violating the Espionage Act. David Petraeus almost did jail time for one count of the Espionage Act.
The final element here is that Hillary has deleted another 30,000 emails that she claims were her personal emails. Who is to know if all of those were personal or not which is why getting ahold of the server was so important. If the FBI can pull up any of the deleted emails, and if those emails were government related or related to Bengazi, or were also classified as top secret, then she is looking at obstruction of justice charges, obstruction of a congressional inquiry charges, criminal conspiracy, and multiple counts of perjury based on the sworn court statement she made just last week.
So if this goes down the way it appears that it may be, then she is in a world of trouble and the least of her concerns will be what happens to her campaign. She will have the fight of her life to stay out of jail.
As far as the lying, that is just par for the course for her.
