Though I do believe that a preemptive pardon is illegal and would be found so by the courts.
Wasn't for Nixon. History disagrees with you.
Really? Last I heard, Nixon, who was never charged, never had is pardon challenged in court by either side. There is zero precedent to prove a pre-emptive pardon is legal or not except that Ford's action was never challenged. I don't think Hillary would be so lucky.
You may think I'm partisan, but what Hillary did with the E-mail thing on a private server IS illegal. Somebody broke the law, apparently multiple somebodies did. It was a violation of State Department regulations, PLUS given the classified nature of some of the e-mails, multiple felonies where committed. Was it Hillary committing these crimes? Sure seems likely to me. Many of the classified E-mail messages she wrote herself, or where sent under her authority as if they came from her. Not to mention that if she even SAW classified data in an unprotected environment it was her responsibility under law, to take the necessary steps to report and secure the information to the best of her ability or it's a felony too.
Now if you wan to believe Hillary's story that she didn't do anything wrong... Well, first you are going to have to pick which of Hillary's stories you are talking about, we are on the fourth or fifth version of this now.... You are going to have to explain how Hillary didn't commit a crime here. Is she incompetent enough to not recognize what classified information was? Was she so stupid that she not know it was being sent over an unsecure channel? You tell me, how does she get out of this, beyond a presidential pardon from Obama?
