Back in 1994, the Democrats were very angry at Newt Gingrich for engineering the Republican take-down that year, resulting in large Republican majorities for the first time in many years. The Dems do what Dems do best, namely, dirty politics. A phone ethics charge was lodged against Gingrich, for which Gingrich was ultimately exonerated...but not before the Democrat media machine has broadcast the phony charges far and wide. The facts of Newt's exoneration were not so enthusiastically reported, often buried in the back pages of major newspapers.
