This has to come to a head before someone else comes in as President. Obama/Jarrett might pardon her. Trump or Cruz - no way.
If Obama refused to pardon her for the sake of the party - a storm like we have never seen before with an avalanche of info would happen.
If he refuses she takes the entire country down, BOTH parties politically speaking. The GOP is in full collusion.
Which is a good thing. Ergo no way he does not issue a pardon.
