Ironically enough, Clinton herself, as a young lawyer back in 1973, actually worked to find grounds for impeachment during the Watergate scandal. According to Wikipedia:
In 1974 she was a member of the impeachment inquiry staff in Washington, D.C., advising the House Committee on the Judiciary during the Watergate scandal. Under the guidance of Chief Counsel John Doar and senior member Bernard Nussbaum, Rodham helped research procedures of impeachment and the historical grounds and standards for impeachment. The committee's work culminated in the resignation of President Richard Nixon in August 1974.
(What would the media's reaction have been if, during the height of the scandal, Richard Nixon had lost his temper and cried out, "What difference, at this point, does it make?!")
In any case, despite the media's relatively gentle treatment of Clinton, poll numbers are showing that the current scandal is hurting her chances for the Preidency.
As they say, karma is a Hillary Clinton.
