If nothing else, looking at the long term picture, Hillary has to be prosecuted from the precedent standpoint. One hundred years from now every pol in the US will have a pay to play foundation. "The Clintons did it" . . not to mention their "I don't recall". . "You have no evidence" . . plead the fifth, . . "I don't remember" . . "Swipe, you mean with a cloth", the various pay to play schemes, giving to China our MIRV technology for campaign cash. . and all the other Clintonisms, not to mention the myriad of other scandals that they've skated through.
There has to be some justice with the Clintons or it will surely happen again. . and worse.
Precedents mean something.
