I kinda sorta think you are correct with a caveat.
The whole Federal Just-us Department is controlled by the whims of a Dear Leader. Similar to the North Korean system. North Korea Lite if you will.
If Dear Leader desires her to carry on his legacy, she will never be prosecuted and actually has a decent chance of being elected, given the nature of the election process.
If dear Leader is still a pissed at her and BJ, she will meet Hilga in the next cell before election day.
We have to face the facts that the rules do not apply to some people. Luckily only a few fit that category for now.
