AT THIS TIME, everything points to Hillary as the benefactor.
This is from the TCU (Texas Christian University) site as is an exerpt from one of the lawyers (Hillary Clinton) employed by the Democrat-controlled Judiciary Committee during the Nixon Watergate era.
The attorney, Hillary Clinton wrote: Impeachment was "one of the tools used by the English" to make their government "more reponsive and responsible". As such, it could be triggered by wrong-doing that was "not necessarily limited to common law or statutory...crimes". Instead, when impeachment had been used in American History, there had been "little emphasis on criminal conduct" but rather simply a need to remove public officials who had "seriously undermined public confidence" through their "course of conduct. "Impeachment", wrote twenty-eight year old Hillary Clinton in 1974, "is the first step in remedial process" to correct "serious offenses" that "undermine the integrity of the office."
As far as I can see, the polls are not working out for the Dems but they are working at it. I'd look for the words "integrity, serious, public confidence" in the polls.
Someplace, a long time ago...maybe about the time that Rathergate came out, I found an article about stating that what Hillary proposed to the Judiciary Committee to take Nixon down was both illegal and unconstitional...but I have not been able to locate it since.
