If she becomes President, it will take an act of Congress to take her off the job, even if she is found guilty.
It would be kinda funny, however. A President serving her presidential term from prison.

It won't come to that. Hillary Fs with a lot of powerful people, and they would have her killed before she can spill any beans. Might think it's extreme, but she's been having a lot of health problems and she can easily be taken out that way, and nobody suspect a thing.
