That a political hack like Gingrich is still around is a clear statement of how deseased our political system is.
E.G:
Ethics violations, charges and fines
In 1989, a U.S. tax court took the unusual step of denying a request for tax-exempt status for a group Gingrich formed, the
American Campaign Academy, whose mission was to train political operatives. The IRS ruled that the academy was partisan because it served "the private interests of Republican party entities rather than public interests exclusively."
In January, 1997 Gingrich faced ethics charges related to his use of charitable organizations to subsidize his partisan political activities. It was revealed that Gingrich and his top consultants had repeatedly attempted to use tax-deductible charitable donations to help promote political goals. The same month, the House of Representatives voted 395 to 28 to reprimand Gingrich, then Speaker of the House, and ordered him to pay an unprecedented $300,000 fine for ethical wrongdoing. Gingrich was charged with using a college course that he taught, called "Renewing American Civilization," to further his political agenda. When the House Ethics Committee questioned him about it, Gingrich made false ("glaringly inconsistent") statements regarding the charges. Five Democrats said they voted "present" -- neither for nor against the reprimand -- because they believed the sanction was not severe enough. It was the first time in the House's history that it had ever disciplined a speaker for ethical wrongdoing.

In December, 1998 Gingrich completed payment of a $300,000 penalty imposed for violations of House rules. Gingrich initially planned to pay the fine with a $300,000 loan from former Senate majority leader
Robert J. Dole (R-Kan.). After Democrats and some commentators argued the loan was a "sweetheart deal" and amounted to a gift, Gingrich said he paid "through wholly personal funds." Gingrich admitted he misled the Committee on Standards of Official Conduct and should have sought better legal advice before using tax-exempt organizations to advance his political goals.
