No one realistically expected Hillary to be prosecuted. It was typical Trump shit talk that people loved at the rallies but no one took all that seriously.
Comey made it close to impossible to prosecute her, first by preemptively immunizing everyone who had evidence and could have been pressured to roll over on her, then by his announcement that no one would prosecute this case. There may be a case against former AG Loretta Lynch and some of the WH officials. Good luck getting all the leftwing democrat attorneys in the Justice Department to do anything with that.
Hillary is finished. We don't need a sideshow. We do need to get rid of Comey and the rest of the FBI leadership.
