I am sorry, Fantom, that you cannot accept political reality, but the media portrayal of Gingrich stuck, and guaranteed Clinton's re-election. And they'd kill him even worse today.
As for Gingrich ... well, he turned out to be something less than honorable, in many different ways.
That was more a result of a weak candidate in Bob Dole, the continued presence of Ross Perot, and the infamous power of incumbency than anything Gingrich did. Remember, Clinton won with a plurality both times.
As much of a weirdo as Gingrich is now—and it is really sad to see what he's become, not just on Trump but a number of issues—Gingrich really did do a good job restoring conservatism to national influence, and his presence was felt for almost a decade after he left (despite the efforts of that perv Hastert and other phony big-government "conservatives" that led to the rise of Obamaism).
