While Gingrich and Bill Clinton are similar in their womanizing and lack of self-discipline, the comparison makes little sense otherwise. When Clinton ran in 1992, he had been a sitting governor for a decade; Gingrich has been out of office for over a decade. Clinton did not hypocritically present himself as a socially conservative candidate. Finally, Clinton rivaled Ronald Reagan in his people skills. There is a reason why he was considered one of the most skilled politicians of his generation. Bill has more charisma in his pinky finger than Gingrich has in his whole body.
Watch this Presidential town hall debate question from 1992. Bush I gives a defensive, totally tone-deaf answer to the question. Then watch Bill Clinton afterward.
