had the same thought. Trump wants to clean up the 'to do' list, take this off it, and by extension, if Barry grants her a pardon, it makes her look guilty while Trump has said no case will be pursued. so it looks bad on Barry's record too.
and once Trump is in office, if more info comes up, then the FBI and DOJ have cause to file charges against an unpardoned Hillary.
"well, we had planned to let this case go away so we can Make America Great Again, but these new revelations demand their day in court."
